Looks like a 2 week old embryo. Intrauterine development of the fetus by week
Before you start counting the term of the proposed pregnancy, you need to get acquainted with two concepts - the real and obstetric term. real term pregnancy is counted from the moment of fertilization. Obstetric - from the first day of the last menstruation. The difference between them is on average about 2 weeks. The sick leave indicates the obstetric gestational age. Therefore, the development of the fetus begins at 3 weeks.
1st week
During this period, fertilization occurred. The fetus is very tiny and it is almost impossible to fix it on ultrasound. Embryo implantation takes place. The restructuring of the body begins and the production of a hormone that is responsible for protecting the fetus during pregnancy. The placenta and umbilical cord are also formed.
There are no signs of pregnancy in the first week. However, some women already feel drowsiness, weakness, heaviness in the lower abdomen. The same symptoms with premenstrual syndrome. hallmark there may be implantation bleeding - small pink or brown discharge.
2nd week
Differences from the first week are insignificant. In the second week, the fetus increases by 1/10 of its total size. The placenta continues to form and begins to function.
There is a pulling pain in the lower abdomen, pink discharge may appear. It is important to consider that abundant brown discharge may indicate a miscarriage. They are often confused with menstruation.
3rd week

The abdomen drops, so the urge to go to the toilet becomes more frequent and there is incontinence.
In some cases, childbirth occurs later than 40 weeks. Often this is due to incorrect calculation of the term.
Already from the eighth day, the fetus can be called a baby, it is no longer just a "foreign body", on the contrary, now the mother's body will completely reorganize in order to create the most Better conditions for bearing a baby.
Why 2 weeks pregnant - different dates for the obstetrician and for the expectant mother?
From a medical point of view, 2 weeks is the period when the last menstruation ends and ovulation occurs. There is no delay yet, the pregnancy itself is hidden. In the second week, the estimated period of menstruation begins. It is then that the delay occurs and the woman begins to suspect about her "special" position.
Many expectant mothers begin to worry about the question, what does the fetus look like? Two weeks is the age when the unborn baby is a lump of cells. Often during this period a miscarriage can occur, which a woman may not even guess about. Spontaneous termination of pregnancy may look like a habitual discharge during menstruation. Sometimes women begin to count the age of the unborn child starting from the delay. However, this is already the sixth obstetric week, and during this period the baby's heart has already been formed.
Pregnancy test
It is still quite difficult to determine 100% pregnancy in the second week, since the hCG level is still very low, and only a test with a sensitivity of 10 units can show the presence of a child. A more reliable way to determine pregnancy is ultrasound. The study will not only confirm the fact of the presence of a child, but also show what the embryo looks like: 2 weeks is still too short a period, but at this moment intrauterine life is already beginning to be felt.
Unborn child immediately after conception
In the second week, the embryo no longer draws nutrition from the egg, but receives nutrients from what the uterus gives it. The development of the fetus in the second week begins with the formation of the tube of the primary intestine for the digestion of food. The embryo after two weeks looks like a group of cells, but already the main features are laid down in 46 chromosomes, which he received from his mother and father.
These days, the heart and blood vessels are laid. By the 14th day of pregnancy in a child, the primary intestine becomes longer and is divided into two parts. An amniotic sac is formed around the embryo, filled with amniotic fluid, which will serve as a protective shell until the end of pregnancy.
The placenta begins to form in the child, connecting the child to the umbilical cord - this is how the embryo begins to look as early as 2 weeks after conception. The placenta is an important organ, thanks to which the child communicates with the mother for 40 weeks. Through the umbilical cord, the child receives useful trace elements, water and oxygen. On the contrary, all unnecessary products are excreted through the placenta by the mother's body. The baby announces its presence by the end of the second week through the hormones of the placenta, which provoke a delay in menstruation. After two weeks, the fetus looks like an egg in which a germinal disc has formed.
The egg is transformed into an embryo: 2 weeks is the period when the growth of the unborn baby is already 2.5 mm.
A child at the 2nd week of pregnancy is actively developing, its cells are dividing, and it gradually descends into the uterine cavity. After two weeks, the fetus looks like an embryo consisting of two bubbles, one of which gives rise to the baby (endothermal), and the other - the placenta and amniotic membrane (amniotic). The development of the fetus in the second week occurs in the graafian vesicle. By the end of this period, the bubble will increase in size and will protrude above the ovary.
Feelings of the mother at the beginning of pregnancy
In the first months of pregnancy, a woman may feel toxicosis more acutely. This is due to the fact that such communication is still being established, and the mother's body is adapting to a new way of life. Toxicosis can manifest itself in nausea and vomiting, intestinal disorders and other symptoms. The presence of such phenomena is more of a norm than a deviation, so you should not rush to see a doctor. At a period of 2 weeks, you can notice other signs of the existence of the embryo:
- increased sensitivity of the breast;
- discomfort in the form of pulling pain in the lower abdomen;
- increase in appetite;
- emotional instability;
- positive pregnancy test.
At the beginning of pregnancy, a woman may feel the desire to apply something warm to the lower abdomen to relieve the feeling of heaviness, but it is important to remember that warming up is contraindicated, especially in this place, it can cause bleeding. The expectant mother should refuse to visit the bath, lifting weights and unnecessary physical exertion.
Some experts advise expectant mothers to treat their teeth during this period. If you do not do this in the second week, you will have to postpone until the second trimester of pregnancy.
The expectant mother throughout the entire period of pregnancy must completely stop smoking and drinking alcohol. In the second week, you can add to the diet vitamin complex with a high concentration of folic acid (or vitamin B9).
If possible, visits to places where you can "catch" an infectious disease should be limited. It is also desirable to limit the use of products that excite the nervous system - coffee, tea, chocolate and convenience foods. The expectant mother should not take medications, only in agreement with the doctor if necessary.
Why does a pregnant woman experience drowsiness? The expectant mother may complain of fatigue or drowsiness, but this only indicates how harmonious the development of the fetus is: 2 weeks is the period when the most important organs of the future baby are laid, which requires increased work of the mother's body.
During the first two weeks, the woman still does not focus on the delay, and the child is already firmly entrenched in the uterus and develops harmoniously. Outwardly, pregnancy is not yet noticeable, but changes in female hormones have already begun.
The onset of pregnancy is the beginning of an amazing time for future mother. Seeing two cherished stripes on the test, I can’t wait to find out what lies ahead on the upcoming path of bearing crumbs. Today we will tell you how the fetus develops by weeks of pregnancy, what the mother feels at the same time, and at what stages all the organs and systems of the baby's body are formed.
Starting point: how to find out when the pregnancy began
The obstetrician calculates the start date for the expectation of a baby in a woman during the first visit to the antenatal clinic.
- The doctor performs a manual examination to determine the size of the uterus. This will help him understand what gestational age the uterus corresponds to.
- Also, the local doctor must specify the date of the first day of the last menstruation. This moment is taken into account, because. the uterine mucosa begins to prepare for pregnancy precisely from this period of time.
- You can find out the most reliable information about the gestational age with the help of an ultrasound examination. An ultrasound study can tell, to the day, when little life began. An examination even at the earliest stages (starting from 4-5 weeks) evaluates the size of the embryo, which allows the obstetrician-gynecologist to calculate the exact date of the onset of pregnancy.
In the first week after conception, the embryo is actively moving through the fallopian tube. After six days of active “journey”, it enters the uterine cavity. Under the action of progesterone (it is also called the hormone of pregnancy), the unborn baby is attached to the uterine mucosa, this process is called implantation.
If the attachment of the embryo has successfully taken place, then the next menstruation will not happen - the pregnancy has begun.
Intrauterine development of the child
The development of a baby inside the mother's womb, from the moment of conception to the moment of birth, is usually called a miracle, and there is every reason for this. Fortunately, medicine has studied quite well all the stages of the most important event in a woman's life - pregnancy. Every expectant mother can accurately imagine what will happen to her and her baby during all nine months.
There are three periods of intrauterine development of the baby:
- blastogenesis- begins with fertilization and lasts 15 days;
- embryonic period- starts from the 16th day and ends by the 13th week of pregnancy;
- fetal period- from 13 weeks and lasts until the very birth.
Each period has its own chronology of events. The formation of the child's organs, vital systems in his body and his immediate growth naturally move in each period of intrauterine development. You can find out how this happens, what and when is formed in the summary table. It will be informative for expectant mothers who are interested and important information about the development of the child at all stages of pregnancy.
The development of pregnancy by week
The expectation of the birth of a baby in obstetrics is usually divided into three conditional parts:
- I trimester - from the beginning of pregnancy to the 13th week;
- II trimester - from the 14th to the 26th week;
- III trimester - from the 27th to the 40th week.
These trimesters contain 10 obstetric months. Conditional split table:
obstetric month | Weekly pregnancy period |
---|---|
First month | From the first to the fourth week of pregnancy (1-4) |
Second month | From the fifth to the eighth week (5-8) |
third month | From the ninth to the twelfth week (9-12) |
fourth month | Thirteenth to sixteenth (13-16) |
Fifth month | From the seventeenth to the twentieth (17-20) |
Sixth obstetric month | Twenty-one to twenty-four (21-24) |
seventh month | Twenty-fifth to twenty-eighth (25-28) |
eighth month | Twenty-ninth to thirty-second (29-32) |
ninth month | Thirty-three to thirty-six (33-36) |
tenth month | Thirty-seven to forty (37-40) |

Now let's move on to describing the development of the baby in the womb for each week of a woman's pregnancy:
Week 1
There is no talk of a fetus as such, since pregnancy has not actually occurred yet. The main sign that fertilization has occurred can be implantation bleeding. This phenomenon manifests itself as slightly spotting spotting approximately 6-7 days after conception.
2 weeks
This week from an obstetric point of view is considered as possible for conception. The egg in the female body matures by the 14th day of the cycle and is theoretically ready for fertilization. If, according to your calculations, the moment of conception has already taken place, then the second week is marked by the attachment of the fetal egg to the uterus. This moment is important, since from the moment of attachment the fetus begins its full development.
3 week
The embryo is similar in appearance to a microscopic berry; in the third week it is still only a set of cells. The size of the embryo is negligible, the maximum diameter by this time is 0.2 mm. But just during this period, the formation of sexual characteristics at the cellular level begins. Having gained a foothold in the uterus, the most important process of intrauterine development of the baby begins - the formation of the placenta. Before the formation and development of the basic systems of the body of the unborn child, there is very little left.
4 week
Obstetric 4th week - the period at which the expectant mother discovers two cherished strips on the test. The functional distribution of cells is in full swing in the embryo. Its size can be compared this week with poppy seeds. The weight is still quite insignificant and does not exceed 0.5 g, but the process of cell division occurs every minute and the unborn baby grows very quickly.
5 week
The embryo has already passed several stages of its development - the zygote, morula and blastocyst. Cells continue to divide rapidly, and by the end of the fifth week, the baby will already weigh at least 1 g, and the size will reach as much as 1.5 mm. On the fetal egg, you can already see the emerging sense organs - eyes, ears and mouth. The blood type of the unborn child was formed just in time for the 5th week of intrauterine life. The formation of the thyroid gland, as well as the intestinal and urinary systems, begins.
6 week
At this time, the largest parts of the body - the torso and head - are clearly distinguished in the unborn child. In the form of tiny processes, legs and arms are distinguishable with tiny fingers outlined on them. The weight at the sixth week of the embryo is up to 2 g, and the average size is about 4 mm. Cartilaginous structures are actively developing, the thymus gland is being formed. The main organs continue to develop: the heart, liver, lungs, stomach and pancreas. The baby develops muscle tissue, the external genitalia are outlined.
7 week
With the beginning of the seventh week, the embryonic period ends. The future baby is now called by another medical term - the fetus. At this time, the facial features of the crumbs are already slightly distinguishable. The rudiments of the nose, eyelids are formed, the ears and upper lip are visible. Outwardly, “unnecessary” organs are still present - gills and a tail, which will disappear a little later. The hemispheres of the brain are formed, cartilaginous tissues are continuously developing. The liver at week 7 is already capable of producing blood cells.
8 week
At week 8, the weight of the fetus is 1 g, and the length reaches 20 mm. If you look at an ultrasound examination, then the future baby will look proportionately like a grape. But every day the fetus looks more and more like a real man. The baby's face is already better defined, the nose has small nostrils, and the olfactory recipes are actively formed. His heart becomes four-chambered; in future girls, ovaries are formed, in boys - testicles; the arms and legs of the fetus at this time can already bend / unbend.
9 week
Many systems and organs are formed by the 9th week of pregnancy, but they do not yet fully function, but continue to develop. Palms are formed, the membranes between tiny fingers disappear. Lymph nodes are laid. The first reflex begins to develop - swallowing. The eyelids of the baby are formed and can involuntarily open and close. The fruit in size already resembles a large cherry berry - weight 4 g, height about 30 mm.
10 week
At week 10, the baby is actively moving and pushing. But these movements are so weightless that the expectant mother simply does not feel them. The muscles of the face, neck and pharynx begin to develop. The face is already formed, and in a few weeks the appearance of the unborn child can be seen on ultrasound. The rudiments of milk teeth develop. The cerebellum "acquires" neural connections, subsequently responsible for reflexes. A small heart makes at least 150 beats per minute. Now the fruit weighs already 5 g, has grown by about +12 mm and resembles a strawberry.
11 week
The organs and systems of the crumbs have already formed by this time, some are working at full strength, while others continue to mature. The bronchi, lungs, trachea are actively developing; liver; intestinal tract; blood vessels; irises of the eyes. At 11 weeks on an ultrasound scan, you can see the outlines of the unborn baby.
12 week
The kid is already actively using some reflexes - imitating breathing and swallowing movements, involuntarily clenching and unclenching his palms into fists. The first contractions of the intestinal muscles (perylstatics) appear. The pancreas is formed and is already “learning” to produce bile. A unique pattern appears on the fingertips. The baby develops facial expressions, he can smile or wrinkle his face. Weight - up to 13 g, and height - up to 62 mm.
13 week
A week of active growth spurt for the unborn baby. The brain is already able to give the first commands to the reflex movements of the fetus. Sense of smell develops, vocal cords are formed. The body begins to grow faster, and the growth of the head, on the contrary, slows down. Digestive villi appear in the intestines of the crumbs. The baby's skin is still very thin, and riddled with blood vessels. The weight of the fetus increases to 20 g, and growth - up to 80 mm.
14 week
At week 14, all organs and systems of the unborn baby are being improved and continue to grow actively. The chest can rise and fall, as if breathing, this is how the lungs are trained. The process of hematopoiesis is formed, sweat glands, neck muscles become stronger every day. The weight of the baby at this time is about 27 g, and the height is 110 mm. The lifestyle, nutrition and well-being of the mother are very important - if these indicators are in order, then the baby feels good and does not experience any discomfort.
15 week
This week, the fetus has already formed vision and the necessary nerve endings to be able to see after birth. From the 15th week, ossification of the skeleton gradually occurs - a long-term process that requires a large amount of calcium. In toddlers, boys begin to produce the male hormone - testosterone. The kidneys excrete the first amniotic fluid. The muscles of the child are improved and strengthened. Fetal weight - 50 g, height - up to 104 mm.
16 week
At week 16, the future baby grows actively from the top of the head to the very heels. The weight is already about 80 g, and the height can reach 117 mm. The systems of the body function to the best of their ability, some of them are already “working” quite smoothly. Swallowing the amniotic fluid, it passes through the digestive tract and kidneys, and turns into urine. The skeleton becomes ossified, the child's legs lengthen. The baby is actively moving in the uterus.
17 week
The auditory formation of the unborn baby by the 17th week is smoothly completed. Weight approaches 100 g, and height becomes about 12 cm. The system of blood vessels develops and branches. The most important components of their own immunity appear in the baby's blood - interferon and immunoglobulin. In female children, the uterus is formed in utero. The strength of the child's tremors increases during this period, they become frequent and tangible.
18 week
The development of the fetus in this period of the second trimester is very intensive. The baby is growing so fast that it could already fit in the palm of your hand. The movements are palpable, the baby moves very actively at week 18. Often swallows amniotic fluid, which can lead to hiccups - this moment the expectant mother can notice by a slight twitching of the abdomen. Gradually, a layer of subcutaneous fat forms in the fetus, muscles develop, and the mineralization of the skeleton continues. Weight - about 150 g, height does not exceed 14 cm.
19 week
The child inside the uterus is actively growing, improving and gaining weight. By the way, by the 19th week the baby weighs about 200 g, and the height is about 14-15 cm. The body emphasizes the development of the brain, the improvement of the five basic senses. The amount of subcutaneous fat increases. The respiratory system continues to develop and strengthen. The period of wakefulness alternates with a period of activity, the baby can sleep up to 16-18 hours a day.
20 week
Outwardly, your baby has already become a real little man, and on an ultrasound scan you can already see the sex of the child, his facial features, watch facial expressions (which sometimes also show the character traits of the future child). The weight of the crumbs at the "equator" of pregnancy is approximately 250-270 g, and the average height is 16 cm. The child is active, turns his head, sucks his fingers, opens and closes his mouth.
21 weeks
At this time, you can already be sure that the child distinguishes sounds and hears what is happening outside the uterus. In terms of body proportions, the baby already almost resembles a newborn. The weight of the fetus is about 300 g, height is 19 cm. At this time, taste buds are actively formed, the composition of the blood is improved.
22 week
The twenty-second week is the period when the unborn child prefers to spend most of his time in a dream. But, nevertheless, in a dream, the baby actively turns over, the size of the uterus still allows you to change position. The baby is spinning, pushing, pulling the umbilical cord. Weight at this stage is about 350 g, and height is 20-21 cm.
23 week
The next week meets with the usual movements, although many babies prefer to “calm down” by 23-24 weeks and make their mothers worry about rare movements. The baby still has enough space in the uterus, so many of his pushes are simply not felt, so you should not worry. The weight is already moving towards the mark of 450 g, and the height is more than 22 cm, although it is worth remembering: all of the above parameters are individual.
24 week
Under the mother's heart, the unborn baby grows and gains weight - the indicator for many future children at this time is at least 550 g. This week, the development of the bronchi in the baby is completed, which is very important for the child's respiratory system as a whole.
25 week
From the 25th week, the child in the womb begins to produce pigment in the hair, giving them the color that is due to heredity. It is this color that the mother will see in the baby at his birth. Weight reaches 700 g, height - 23-25 cm. Nerve connections and brain cells continue to form. In the fetus, training respiratory movements can be observed.
26 week
Tremors for a period of twenty-six weeks become strong, distinct, and many mothers may even complain about their intensity. The weight of the child is already at least 800-850 g, and the height is already more than 33 cm. The active strengthening of the bones of the skeleton continues, the rudiments of milk teeth in the gums are mineralized. Nails and hairs begin to grow.
27 week
The growth of the child at this time is about 34 cm, and the weight is approaching 1 kg. The baby becomes cramped in the uterus, and the legs can no longer be stretched out, so the baby takes the optimal position: it pulls small crossed legs and arms to the chest. From the twenty-seventh week, the baby is already gradually assuming the correct position in the uterus, but if he lies across or “sits on the priest”, then there is still time to roll over.
28 week
From the beginning of the 28th week of pregnancy, the weight of the fetus is up to 1300 grams, and the height is up to 37 cm. The development of muscle tissue continues intensively in the child. New convolutions are formed in the cerebral cortex. A Rh conflict between the mother and the fetus is possible, and at this time the obstetrician-gynecologist must take special measures.
29 week
The weight of the fetus is about 1500 kg, and the body length is at least 38 cm. It is time for the expectant mother to master the method of counting movements.
30 week
The full growth of the fetus reaches 36-38 cm, weight reaches 1.5 kg. The expectant mother may have several fears that are associated with future childbirth.
31 weeks
At the 31st week of pregnancy, the weight of the fetus will be about 1.6 kg, the full height is about 39 cm. The baby develops pain sensitivity. There may be disturbances in the night's sleep of a pregnant woman due to active and strong fetal tremors. It's time to explore the issues of anesthesia during childbirth.
32 week
The weight of the fetus is about 1.7 kg, the size from the crown to the heels is 40-42 cm. Sudden movements can cause dizziness and nausea in a pregnant woman. It's time to think about the possible presence of someone close to you at the birth.
33 week
The weight of the fetus by week 33 is approximately 2000 g, height is 42-43 cm. The mineralization of the bones of the fetus is almost complete. The expectant mother should from time to time count the movements of the fetus.
34 week
The growth of the fetus is on average 43-44 cm, weight 2.2 kg. The baby becomes very crowded in the uterus, and motor activity decreases. It's time for mom to discuss with the doctor the method of delivery: natural childbirth or caesarean section.
35 week
Fetal growth 45-46 cm, weight 2300-2500 grams. The fetus is almost completely ready for childbirth, but the lungs are not yet ready to perform the respiratory function. It's time to pack your things for the hospital. If the baby in the uterus has not yet taken the correct position, special exercises will help.
36 week
The weight of the fetus is approximately 2.5-2.7 kg. Full height is about 45-47 cm. At this time, the indicators of each crumb can differ greatly from the average, up or down. It's time for parents to make a list of things to plan and complete before the baby is born.
37 week
The thirty-seventh obstetric week of pregnancy is the time when the mother must be mentally prepared for the birth of the child. This is especially true of multiple pregnancy and the birth of children, starting with the second child. The weight of the child reaches 2.9 kg, and the growth is within 50 cm.
38 week
The thirty-eighth week may be the last week of your pregnancy. The child gradually becomes heavier. The baby weighs about 3 kg, and the height is already 48-50 centimeters. Childbirth can begin at any time, so loved ones must be within reach at all times.
39 week
At the 39th week, the mother is not only physically, but already mentally prepared for childbirth. The baby weighs about 3 kg, and its height is about 48-50 cm. In size, the child at this time is similar to a miniature watermelon.
40 week
At the end of this week, the expected date of the birth of the baby may fall. The weight of the baby is already about 3.5 kg, height is about 51-55 cm. The baby is completely ready for birth. It remains to wait for the moment when he will make the newly-made parents happy with his birth.
Total.
This is how 40 weeks of pregnancy goes. A happy start to a new life - watch the video of how the baby develops in the mother's stomach:
Pregnancy development by months: how the mother's body changes and the baby grows
1st month
Mother. The chest becomes sensitive, touching it is painful. The uterus begins to grow gradually.
Child. So far, the future baby is called an embryo. For the first six days of pregnancy, he swims in the amniotic fluid, lives “autonomously” and is not yet connected with his mother. Outwardly, the embryo resembles a tiny auricle measuring 5 mm in size. By day 21, his heart begins to work; in parallel, at the same time, important organs are formed: the spinal cord and brain. By the end of the 1st month, the umbilical cord appears, connecting the baby with the future placenta.
2nd month
Mother. Pregnancy is outwardly not yet noticeable to either the expectant mother or others - the uterus is in the small pelvis, and its size is small. Changes continue to occur in the breast, it swells and increases in size.
Child. This month, changes are coming in the appearance of the unborn baby - facial features are emerging, the outlines of the eye sockets appear; there is the formation of tiny arms, legs and even fingers on them. The weight of the embryo at this time is up to 8 g, and the size is about 4 cm.
3rd month
Mother. An intensive growth takes place in the uterus, it develops, it already fills the small pelvis in size and almost reaches the womb. Very soon everyone will see that you are in position!
Child. By medical standards, your baby has already passed the embryonic stage and is now becoming a fetus. Its weight can reach 65 g, and its length varies from 10 to 12 cm. An important point in development is that in the 2nd month, the child has an inner and outer ear. The baby behaves very actively, moves its arms and legs, nods its head and clenches its fists. The growing child already has eyelids, and thanks to them he can open and close his eyes.
4th month
Mother. A rounded tummy is already looming, the waist begins to gradually “blur”. The mammary glands cause considerable discomfort due to their growth and sensitivity - you have to choose a suitable sleeping position for a long time.
Child. Your baby already has quite a tangible weight - up to 250 g. Most of the time the child spends swimming in amniotic fluid ah, they update every 3-4 hours. A fluff appears on the baby’s head, eyebrows and eyelashes appear on the face. In the intrauterine process of development, the first feelings and sensations begin to form in the child. The baby reacts to loud sounds and to a bright light source.
5th month
Mother. Almost every day, the belly of the expectant mother becomes larger and clearly protrudes forward. The uterus is located about 8 cm below the navel. Starting from 17 weeks, most expectant mothers begin to feel new sensations in the stomach - so far weak, but very pleasant jolts and movements of their baby.
Child. In the fifth month, the child's brain is actively growing, the nervous system is developing. The heart beats more often 2 times than that of the mother. The weight of the crumbs by this period can be up to 650 g, and the height is about 30 cm. By the 20th week, the baby is already able to suck his fingers on his hands, and at 24 weeks he can open his eyes and react to light.
6th month
Mother. The waist of a pregnant woman by this time becomes 8-10 cm larger. The size of the uterus increases so much that now it reaches the navel. The state of health and mood are good, the weight has not grown too much and nothing limits the activity of the expectant mother.
Child. It is time for the maturation of the respiratory system of the baby. The lungs begin to mature after 24-25 weeks of pregnancy. The child has already formed sensations of light and noise - when a sharp sound is heard, the baby may shudder. The first reflexes (hiccups, swallowing and sucking reflex) also appear and actively develop.
7th month
Mother. The size of the uterus by the seventh month of pregnancy reaches 24-28 cm in height, it continues to grow and increases with the child.
Child. The baby is already less active than at an earlier date. In most cases, the baby settles in the uterus head down, and sleeps for a long time. The weight of the child is already 1-1.2 kg, and the height is up to 37 cm. He is already learning to breathe, but the lungs are not yet mature enough - they will finally be ready for the breathing process at about 34 weeks, which is important for premature birth. By this time, the baby has already learned to recognize the mother's voice, and recognizes it when he hears it.
8th month
Mother. The body of the expectant mother continues to change - the uterus rises already by 30 cm, contracting from time to time, as if “rehearsing” the upcoming contractions. Colostrum appears in the breast. In the third trimester, the load on the female body increases many times over, and existing chronic diseases may worsen.
Child. The baby is growing and gaining strength. For bone mineralization, the baby needs a large amount of calcium, which comes to him from his mother. The skin of the child becomes pink, smoother. From time to time, a mother can observe protrusions and “bumps” on her stomach at those moments when the baby is tossing and turning.
9th month
Mother. The body of a pregnant woman begins active preparation for childbirth. The uterus, together with the baby, weighs about 6-7 kg at this time, and its height is measured within 33 cm. In the third trimester, pain in the pubic joint, swelling and increased blood pressure are not uncommon.
Child. After the 38th week of pregnancy, the development of the intrauterine development of the baby can be considered complete. The baby is ready to be born. In the last month, the baby is gaining 10-15 g daily. Amniotic fluid is becoming less and less, the child is growing by leaps and bounds, and it becomes crowded in the uterus. In girls, the large labia cover the small ones; in boys, the testicles descend into the scrotum. The fluff on the body completely disappears, and little original lubrication remains. At the time of birth, the child weighs approximately 3-3.5 kg, and the height varies from 50 to 55 cm.
And finally, photos and recommendations from a young mother. Look at the photo of the growth of the abdomen during forty weeks of pregnancy. Have you photographed your belly week by week?

3 weeks pregnant. The development of the fetus and the feeling of the mother at 3 weeks of gestation.
In the third week of bearing a baby, an immunosuppressive protein is produced, which is called the first sign of pregnancy. Without it, the human body could confuse the embryo with a foreign body and reject it. Even a small amount of this protein will be enough for the test to confirm pregnancy.
During this period, the fetus still does not look like a child at all. Outwardly, it is rather a cluster of cells that can only be seen with a powerful microscope. However, the embryo already has genes that determine its height, sex, external features, as well as the individual traits of the child. Even despite the fact that in the first weeks of pregnancy the human fetus practically does not differ from the embryo of any animal, by the end of the first trimester it will be possible to accurately determine its legs, arms, head. In the third week, the laying of all internal organs begins. The first to form are the heart, reproductive organs, and neural tube. On the twenty-first day of bearing a child with an ultrasound examination, it is already possible to fix the heartbeat of the embryo.
Signs at 3 weeks pregnant
In the third week of pregnancy, a woman has the first signs of pregnancy. allowing to predict its interesting position. Some expectant mothers experience increased sensitivity, a change in appetite, fatigue, or pain in the chest area. During this period, many women become quick-tempered, irritable and whiny. All these changes are explained by significant hormonal changes that cause a restructuring of the work of all higher nervous activity and the formation of the predominant dominant of pregnancy.
At the beginning of pregnancy, many sensations are similar to the symptoms of the second half of the menstrual cycle. Under the influence of the hormone progesterone, fluid retention occurs in the body, which is why some women feel pulling pains in the lower abdomen. In the first weeks of waiting for a baby, the amount of discharge from the genital tract may change. In some women, they are rather scarce, while in others they are quite plentiful. But despite their number, the nature of such secretions must necessarily correspond to the norm. In a healthy woman, these discharges are light milky in color and have a slightly sour smell. Any deviation from the norm may indicate the presence of various infections in the body and is an urgent reason for a visit to the doctor.
A common occurrence at the very beginning of pregnancy can be early toxicosis. Due to improper removal of toxins, a woman may be accompanied by both mild nausea and severe vomiting. However, most expectant mothers at such an early date still do not feel any changes in their bodies and lead a normal life. During this period, it is advisable to avoid x-ray examination, you should not take any potent drugs. In the third week, pregnant women are prescribed folic acid, as well as vitamin E. Despite the fact that a new life is born in a woman’s body, there is no need to eat for two at all. The required daily dose of nutrients is 2200 kcal. However, it is better if daily ration be divided into five or six meals. But for a snack, fresh or dried fruits, berries or nuts are perfect.
Any pregnant woman, and especially one who is in the early stages, needs additional proteins, iron and calcium. All these substances are contained in sufficient quantities in cottage cheese, fish, broccoli, apples, fresh vegetables and fruits, as well as in wholemeal bread. Be sure to drink enough clean water. The required dose is one and a half to two liters per day. But the amount of strong tea or coffee you drink should be reduced to the minimum portion. Under a strict ban is alcohol and nicotine, because even their minimum dose can cause irreparable harm to the life and health of the child.
Weekly pregnancy calendar:
2-3 weeks pregnant
If you are expecting pregnancy. then you will undoubtedly be interested to know what processes excite your body in the first weeks after conception.
At 1-2 weeks of pregnancy. as well as in 3 and 4, the intrauterine development of the baby takes place in an active way. During the first week, the embryo travels through the fallopian tubes and is implanted in the wall of the uterus, and then the body of the embryo begins to acquire the necessary shape and structure.
Ultrasound pregnancy 2-3 weeks. mainly carried out by a vaginal probe. The appearance of the embryo can now be compared with the auricle, and its size is only 4 mm.
AT 2-3 weeks gestation period still small, but some women can guess by indirect signs about their interesting position. A woman may feel dizzy, general weakness may appear, her mood may change many times a day.
To 2-3 weeks of pregnancy featured can be attributed to the changes that occur with the chest. Under the influence of a changed hormonal background, the breast increases in size and becomes quite sensitive. The first heralds of upcoming toxicosis may appear - a change in taste preferences and nausea. Of course, they may not be observed in every pregnant woman.
If, nevertheless, nausea has tormented you, then try to eat a green apple every morning, even before breakfast, without getting out of bed. Food should be fractional (however, as throughout the entire term of pregnancy) - eat often, but little by little. The diet will also have to be changed - believe me, this will benefit your future baby and significantly improve your well-being at the moment. Give up fried and fatty foods in favor of salads and dairy products. But if you still have a desire, then do not deny yourself a small amount of pickles or sauerkraut.
It’s good if in the first days of pregnancy the expectant mother leads an active lifestyle, it’s good if the woman both visits theaters and museums and walks in the fresh air - the baby needs as many positive emotions as possible, which he will also feel, because the hormonal background of the mother will become special.

Embryo 2 weeks
Although in obstetric practice it is believed that pregnancy has not yet occurred in two weeks (it is not considered an actual pregnancy), an embryo at 2 weeks already begins to live its own life and develop according to its term. After all, from the first hours of conception, fertilized egg has a developed mind.
Immediately after the fertilization of the egg, which occurs in the fallopian tube, the crushing of the zygote - the fertilized egg - begins. After making its way through the fallopian tube, on the fourth day the fetal egg turns into a blastocyst. In the uterine cavity, the blastocyst approaches the site of egg implantation - penetration into the uterus, this process lasts about 2 days. By this time, the egg settles on the uterine mucosa and, with the help of chorionic villi, is firmly attached to the uterine mucosa.
Human fetus 2 weeks
The human embryo, 2 weeks old, is in the Graaffian vesicle. It has not changed much after the process of conception, it has already formed extra-embryonic organs - amnion, chorion, yolk sac, which all provide it the necessary conditions for further development. At 2 weeks, the fetus forms the cell nuclei and cytoplasm. By the end of 2 weeks, the embryo becomes a mature egg, which has a nucleus, formed cytoplasm, a shiny transparent membrane and is “decorated” with a crown of epithelial cells.
2 weeks pregnant - fetal size
As studies show, the size of the embryo at 2 weeks is still impossible to measure, as well as the weight of the child at 2 weeks. The first size that can be determined - 0.15 mm, was recorded at the third week of pregnancy, and the weight - 1 g - only at 8 weeks.
Fetal development at 2 weeks
To maintain a pregnancy, you must follow drinking regime, diet, i.e. provide the unborn child with everything necessary for proper development. Under unfavorable conditions for development, a 2-week-old embryo may not implant and will be released along with menstruation. And the woman will never know that she was pregnant. Such adverse conditions can be nervous stress, physical activity, medication.
What does a 2 week fetus look like?
To find out, it is enough to do an ultrasound, which will not only show what the embryo looks like, but also accurately determine the duration of pregnancy. Even though the embryo is not yet visualized. During ultrasound, you can determine the heart rate.
The embryo is 14 days old already has consciousness, vital organs are being formed in it, its heart can be heard. It's not just a fetus. This is your future baby, who will be born in 38 weeks.
» Second 2nd week of pregnancy
Embryo 3 weeks
The embryo at the 3rd week of pregnancy is at the very beginning of its life path, it survived conception, attached to the walls of the uterus and primary cell division begins. The age of the embryo at 3 weeks of gestation, according to obstetric calculations, is only seven days, and the expectant mother is not even aware of its existence.
The life span of a fetus of 3 weeks is calculated in different ways and can be equated to 5 obstetric weeks or seven days from the absence of the last menstrual cycle. This is what is the impetus for a woman to purchase a pregnancy test or visit a gynecologist. There is a chance to get rid of the fetus in 3-4 weeks of gestation with virtually no consequences.
However, no matter how small the fetus is at 2-3 weeks, it already has a huge impact on the mother's body by its presence. Special hormones begin to be released that will protect and support the baby throughout the entire gestation, breast engorgement, signs of early toxicosis, and so on. A positive pregnancy test becomes a source of desire to know what the fetus looks like at 3 weeks and what it is.
Fetal ultrasound at 3 weeks
A transvaginal study of fetal development at 3 weeks will in no way tell about the presence of any malformations in development, and is prescribed in exceptional cases:
- there is a risk of interruption of gestation;
- a woman notes pain in the abdomen or discharge from the genitals;
- signs or symptoms of ectopic attachment of the ovum.
What does an embryo look like at 3-4 weeks?
At this time, a child is just a group of growing and constantly dividing cells that are just beginning to “fold” into a future little man. The size of the embryo at 3 weeks is only 16 millimeters, and the weight is 1 gram. Pawned organs may not withstand the appearance of any defect and give complications that are not compatible with later life. The baby is now sickle-shaped, and an experienced uzist will determine the location of the future tummy or back. The nose is represented by folds, there are rudiments of auricles and cartilage of the future skeleton. The end of the third week is marked by the formation of the heart muscle and its first contractions. The embryo is in a small fetal sac and is surrounded by amniotic fluid. Therefore, before the eyes of the expectant mother, only a bright spot will appear on the monitor screen, which will please the first heartbeat.
The surest signs of pregnancy in the 3rd week
The agonizing expectation of the baby and the question of whether there is a pregnancy or will have to wait a little again is finally resolved in the third week after the alleged fertilization.
What does the fetus look like in the early stages?
The conception of a child occurs in the third week of pregnancy (obstetric). That is, gynecologists begin the countdown from the first day of the last menstruation, when a new cycle of ovulation began. After the fusion of the maternal and paternal cells, a complete embryonic cell, or zygote, is formed, which contains all 46 chromosomes. On the first day after conception, the zygote begins to fragment intensively. At the same time, the zygote itself does not increase in size when it gives rise to new cells. On the third day after conception, the baby's embryo, which already consists of 12-30 cells, reaches the uterus. Here it is in a free state for some time, and at the end of the third week, implantation occurs in the uterine mucosa; during this period, a woman may feel the first symptoms of pregnancy.
The body of a woman in early pregnancy
The female cycle first forms the corpus luteum, which is made up of luteal cells that produce progesterone. If conception does not occur, then the corpus luteum begins to develop in the opposite direction and menstruation occurs. When fertilization occurs, the corpus luteum transforms and begins to perform another function - it produces progesterone, which maintains the pregnancy until the moment when the placenta is formed. From this moment on, changes occur in the female body that prepare for the implantation stage: the mucous membrane of the uterus becomes thicker, more loose, in order to receive the embryo. By the end of the third week of pregnancy, the zygote is fixed on the wall of the uterus, plunging into the mucous tissue of the mother's womb; from that moment on, a woman can say "I'm pregnant." The implantation period lasts about 40 hours, after which the development of the embryo moves to a new stage.
Definition of pregnancy in the third week
Roughly speaking, the pregnancy itself begins from the third week. From the moment of conception in the mother's body, the restructuring of the functions of organs and systems under the influence of hormones begins. Already a few days after conception, the expectant mother may feel the first signs of her situation. Obviously, a woman suspects that she is pregnant if she has a missed period in the third week after ovulation. Sometimes in women who aspire to motherhood, pregnancy symptoms can occur for no reason, only against the background of the state of the nervous system. From the third week of pregnancy, a woman may feel changes in her appetite towards its intensification, which is expressed in a feeling of insatiable hunger. Or, on the contrary, from the very first days of a new state, a woman loses her desire to eat. Taste preferences can also change: favorite dishes give way to unusual foods, such as dry pasta or unripe apples. In most cases, there is an aversion to smells - a sign of pregnancy, which is already present in the first three weeks. The fact is that the third week from conception corresponds to the fifth obstetric week, and during this period a sufficient amount of the hCG hormone is already produced, which is a symptom of pregnancy.
For a woman who dreams of saying the phrase "I'm pregnant," three weeks after conception is the time when you can confidently diagnose, even with the help of test strips. The most reliable result can be obtained when the third week from conception comes. Pregnancy symptoms are more pronounced at this time.
Feelings in the third week of pregnancy
There are also changes in the emotional state of the future mother - she becomes more irritable, tearful. This is due to a change in the level of hormones in the body, which causes a restructuring of the nervous system and produces a dominant pregnancy. Most women note changes in the mammary glands as one of the symptoms of pregnancy in the second or third week after conception. The breast becomes heavier, it becomes larger, but these changes are similar to those that a woman feels during the menstrual cycle. The first signs of the third week of pregnancy are almost identical to the sensations experienced by the female body at the end of the menstrual cycle. Some women note breast enlargement, which is associated with the production of progesterone. This hormone is responsible for retaining fluid in the body of a woman, so a pregnant woman may feel pulling pains in the lower abdomen. The discharge of each woman in the third week of pregnancy is individual. Some note an increase in their number, others, on the contrary, note their scarcity. However, their character should correspond to the norm: they should be light milky in color, be uniform and have a slightly sour smell.
If a girl sees that her mark on the gasket is different from the description, she should consult a doctor. Deviations may indicate that there is an infection in the genital tract. Signs of pregnancy in the third week tell the expectant mother that huge and important changes who will make her life happy with motherhood nine months later.

3 WEEK PREGNANT
It is this week that can be considered the beginning of a real pregnancy, because just at this time the fetus finally appears. So far, of course, he still does not look a bit like a future child, but this is an already formed embryo that will develop over the coming weeks.
So, conception happened at the end of last week. In the third week, the fertilized egg - the zygote - is still in the fallopian tube. For seven days, it actively develops into a multicellular embryo, simultaneously making a continuous movement towards the uterine cavity, in order to attach to its wall at the end of the week.
Fetal development
The growth of the embryo this week is simply rapid. In just three days after fertilization, the egg will turn into 32 cells, and by the end of the week, the embryo consists of 250 cells! Obstetricians call the embryo at this stage a blastocyst.
While your unborn baby, now more like a mulberry or a bunch of tiny balls, moves towards the uterus, he feeds on his own energy reserves, as well as on the protein compounds secreted by the glands of the fallopian tubes. But already on the 6-7th day after fertilization, the blastocyst will enter the uterine cavity and try to gain a foothold on its inner shell. This process is called implantation - the embryo sinks into the layer of the endometrium, breaking the mucous membrane of the uterus and, as it were, pulling out a small mink for itself in the tissues of the uterus. During implantation, microbleeding is possible. Often, noticing such spotting in the third week of pregnancy, women mistakenly take them for menstruation and believe that the pregnancy has not occurred. In fact, the opposite is true - from the moment of implantation, a strong connection is established between the embryo and the mother's body, from now on, the fetus will receive all the necessary substances from you.
Mom's condition
When the third week of pregnancy comes, the sensations of the expectant mother can be very similar to the approaching menstruation - fatigue, drowsiness, increased sensitivity of the breast, even slight discharge is possible. Since there has not yet been a delay, many attribute these symptoms to PMS, not knowing about their pregnant condition.
What to do this week
If you found out about pregnancy just now - re-read all the recommendations that apply to 1 week. and start doing them. Especially relevant at this time is the intake of folic acid, iron and vitamin E. It is also possible and necessary to take iodomarin.

Pregnant women are interested in knowing what happens in their body immediately after conception. 2-3 weeks of pregnancy is the period when the baby begins to develop rapidly. The stage of egg implantation in the uterine wall has been successfully completed. The active formation of all systems and organs of the child begins. During this period, a woman may still not know about the onset of pregnancy or only guess. The lifestyle remains the same. Some women may continue to smoke or drink alcohol. Later, when they learn about the pregnancy, they worry about the health of the child. How serious can be the harm caused by bad habits in the very first days after conception?
Pregnancy at 2-3 weeks what happens
At the end of the first and throughout the second week after the moment of conception, the fertilized egg is immersed in the wall of the uterus. At the same time, the formation of the chorion, a branched membrane, begins. With its help, the embryo is attached to the wall of the uterus. Over time, the placenta will develop from the chorion, through which the baby will receive the necessary nutrients, including oxygen. Until the end of the second week, the laying of the fetal organs has not yet begun.
A fertilized egg at this moment is very vulnerable, and any negative factors can destroy it. If at this moment you get poisoned with alcohol or get sick, the egg will die. But if the egg survived, then the negative factors turned out to be insignificant in strength. They also did not affect the development of the child in any way, since he had not yet begun to form. Thus, if the pregnancy continues to develop successfully, it is not worth worrying about the harm to the unborn baby at this stage.
Starting from the third week, the process of embryo development starts. In the period from 3 to 13 weeks, the laying of all human organs and systems takes place.
It is called the period of organogenesis. Any harmful factors at this moment can cause serious harm to the fetus, cause a failure in the formation of one or another organ and lead to a pathology in the development of the fetus.
What specific organ will be damaged depends on the gestational age and the influencing harmful factor.
What does a woman feel at 2-3 weeks pregnant
At this time, many women are already aware of their interesting position.
In addition to delaying critical days, a pregnant woman begins to experience various ailments. You may experience mild dizziness, mood swings, or weakness. Some women complain of drowsiness. As a rule, during this period, women already pay attention to changes in the breast. The chest can become painful and sensitive, it can burst from the inside. At such an early stage in pregnancy, a woman may suddenly and very strongly want some kind of dish. Or, conversely, categorically refuse to try some product. These are harbingers of the upcoming toxicosis. They indicate that the pregnancy hormone is successfully produced. However, quite a lot of women do not notice any discomfort during this period.
How to determine the onset of pregnancy
Whether a woman has ailments or not, but in the third week of pregnancy, a delay in menstruation is already obvious. Therefore, at this stage, many run to the pharmacy for tests to determine pregnancy. Research with the help of the test at this moment gives, as a rule, the correct result. The hormone in the urine is already enough to modern tests were able to catch him. The main thing is that during the procedure the woman correctly fulfills all the requirements of the instructions that are attached to the test.
A positive test result warrants a visit to the doctor. The doctor will examine the pregnant woman, determine the approximate gestational age and calculate the estimated date of delivery.
How obstetrician-gynecologists determine the gestational age
Most women mistakenly count weeks of pregnancy from the date of the first day of missed periods. Therefore, they may be very surprised when the doctor determines a much longer period than expected. In the understanding of the obstetrician-gynecologist, the period of 1-2 weeks of pregnancy is the period when menstruation ends and the body begins to prepare for ovulation. No conception has yet occurred at this point. This period is called 1 and 2 obstetric weeks. The countdown of the obstetric gestational age begins with them. Since conception occurs approximately 2 weeks after the start of the last menstruation, the obstetric period differs from the real one by 2 weeks. Obstetric pregnancy lasts 40 weeks. And the embryo develops at 38 weeks. These are two different methods of calculating the term. Thus, 2-3 embryonic weeks of pregnancy correspond to 4-5 obstetric weeks. In their practice, doctors use obstetric terms, and everywhere only these numbers will appear in the records.
Ultrasound at 2-3 weeks of pregnancy
After visiting the doctor, a woman can go for an ultrasound examination, which allows you to confirm the presence of pregnancy and more accurately determine its duration. Also, the specialist will identify multiple or ectopic pregnancy.
Ultrasound at this early date is often performed transvaginally by inserting a transducer into the vagina. This method allows you to view all the necessary details from a closer distance.
Ultrasound is prescribed only if the doctor has any concerns about the woman's health. The first scheduled ultrasound is usually done later.
How to survive toxicosis easier
Pregnant women in summer and autumn were more fortunate. During this period, there are many products that help make it easier to endure the torment of the first weeks. The best way to reduce nausea is to eat more fruit. It is good to eat some juicy apples every day. It is recommended to start the day with an apple.
It is better to take the first meal in bed before nausea sets in. Breakfast should not be plentiful, but satisfying.
Meals can be made more often, but in small portions. It is good if the menu has a lot of fruits and vegetables. From such food, nausea is not so strong.
No need to force yourself to eat unpleasant foods. You can replace the fish with white meat chicken or rabbit. If soups are disgusting, you can refuse them for a while. Dairy products, as a rule, are easily tolerated with toxicosis.
Do not abuse cabbage and grapes. These products cause fermentation in the intestines and can cause a miscarriage in a very short time.
But if there is an unbearable desire to eat some kind of harmful product, you should not deny yourself. You just need to try to eat the minimum portion. As a rule, a small piece or a few sips is enough for pregnant women to satisfy the desire.
Lifestyle changes
The new position obliges to change the habitual way of life. If there is the slightest suspicion of pregnancy, it is necessary to act as if this fact has already been confirmed. If the alarm turns out to be false, the body will only benefit from this.
Smoking and alcohol should be stopped immediately. Do not abuse coffee. In addition, you need to limit your stay in smoky rooms as much as possible. Rooms with polluted air should also be avoided. You need to be outdoors more. The dwelling should be regularly ventilated and not get carried away with air conditioning.
If a girl is used to intense sports, it is recommended to significantly reduce the load.
It is necessary to categorically refuse any drugs, no matter how harmless they may seem. Medicines should be taken only in emergency cases under the supervision of a doctor. It is strictly forbidden to prescribe medications on your own. Only a doctor can realistically assess the degree of harm to the embryo and the threat to the woman's health. He will select the most gentle treatment option.
You also need to review your diet. From it, without regret, you need to remove all harmful products. Nutrition should be filled with natural vitamins and minerals as much as possible. It should be varied, rich in proteins. Proteins are a building material, so there should be a lot of protein products on the menu.
A woman and her relatives should understand that the health of the unborn child depends entirely on them.
3 weeks pregnant has arrived. What new will appear these days in a woman's life? What joys and anxieties are associated with this time? Most important points, information and advice - everything for expectant mothers.
Two perspectives on time
For convenience, any doctor will count from the first day of the woman's last menstruation. The concept of obstetric term is based on this system. According to another system (embryonic), the period is considered from the middle of the cycle. It is at this time that ovulation and conception most often occur.
In obstetric practice, the third week is the period of fertilization. The egg is mature and moves to the uterine cavity. At some point, a spermatozoon penetrates into it, and then the zygote will continue to move. This new cell has a complete set of chromosomes and is capable of dividing very quickly.
According to the embryonic method, once a single cell already develops vigorous activity and actively lives its own special, hidden life. And the expectant mother? If she does not yet know exactly about her pregnancy, then she probably guesses. After all, she has already delayed her period for about a week.
In order not to get confused in the lines, we read a detailed article about this (terms of pregnancy: obstetric and embryonic).
From conjecture to certainty
Three weeks after conception, a pharmacy test will show those same two strips. At the same time, the level of the hCG hormone in the woman's body will increase. An appropriate blood test will confirm pregnancy. But if we talk about the obstetric third week, the pregnancy has barely come and is still not determined in any way. Moreover, a woman can still have her period.
According to medical research, 70-75% of fertilized eggs are rejected. by the female body even before fixing in the uterine cavity. This happens for a variety of reasons:
- initial cellular defects;
- hormonal disorders;
- infectious diseases;
- stress.
Sometimes rejection occurs without any prerequisites at all. Since the embryo has not actually begun to develop, this phenomenon is not considered a miscarriage. A woman may, in principle, not know about what happened. For her, one day, another menstruation will simply come.
unwanted pregnancy
The third week from conception is the time for making a decision if the pregnancy was not only not planned, but also not allowed. Everything happens in life. In fact, no method of contraception is 100% guaranteed. And sometimes partners treat this important issue carelessly.
In any case, if you interrupt unwanted pregnancy, right now. Only the decision to have an abortion should be considered and accepted with full responsibility. Any actions should take place under the instructions and under the supervision of a doctor. "Amateur" here can lead to the most adverse consequences.
Feelings of a future mother
In the third obstetric week for a woman, everything goes as usual. But three weeks after the conception of new experiences, there can be a lot.
For example, a woman begins to accurately recognize the smell of dark and light grapes. Even if before she could not boast of a delicate sense of smell at all. And then she begins to be madly annoyed by the smell of the toilet water of her beloved man.
Food tastes may also change. Sauerkraut or cucumbers become perhaps the most delicious foods, and your favorite kind of cheese suddenly causes disgust. Perhaps this is a prelude to taste quirks. Among future and accomplished fathers, there are whole legends about wives who ate herring with sour cream or demanded strawberries in February.
And the most active and lively woman suddenly turns into a “sleeping beauty”. It seems to be a complete rest, and there is no overwork. But at the same time, more than anything else, I want to sleep.
All such sensations arise in a woman due to hormonal and physical changes. The body is hardwired to work in a special mode.. Also, the expectant mother may note:
- increased sensitivity of the breast, especially the nipples;
- frequent visits to the toilet due to relaxation of the smooth muscles of the intestine and increased activity of the ureters;
- periodic constipation;
- nausea (which may result in vomiting).
What will people around notice?
There are no objective signs in the third obstetric week, but they can be very noticeable with the embryonic approach. A test or blood test must have been done, confirmation received. Thoughts about the baby can significantly affect the appearance of the expectant mother. She becomes more feminine, graceful and seems to bloom.
However, at the same time, a woman can suddenly “break loose”, become irritated. Relatives or close people will see a noticeable increase or decrease in appetite.
During a medical examination, the doctor will note specific symptoms: breast swelling and an increase in the size of the patient's uterus.
Embryo or fetus? What's going on inside?
From an obstetric point of view, a full pregnancy has not yet occurred in the third week. Meanwhile, the uterus is preparing to receive a fertilized egg.
If the embryo has not yet settled in the uterine cavity, now it will definitely happen. The whole process is quite complicated, it takes about forty hours. First of all, the embryo produces a particularly important immunopressor protein. The fact is that half of the cells of the embryo are foreign to the mother's body - after all, they "came" from the father of the child. Without a special protein "signal", the uterus will never accept the future fetus - immunity will not allow it.
The fixation of the embryo in the uterus gives rise to another important process. it placentation. Through it, the fetus in the womb receives all the necessary nutrients.
What does the future baby look like? So far, it's pretty prosaic. The embryo is in the morula stage - a dense rounded lump of cells. The morula rapidly develops into a blastocyst. This means that a cavity with fetal fluid is formed inside the lump, in which the baby will then develop.
The size of the fetus (embryo) is negligible. By the end of the third week after conception, it has a diameter of 0.1-0.2 mm, and its weight is 2-3 micrograms (mcg, one thousandth of a gram). And in this tiny grain of sand there are already about 250 living cells. Very soon, the formation and development of the main systems of the fetal body will begin, and the tiny heart will count its first beats.
Ectopic pregnancy
The term seems to speak for itself. Theoretically, in addition to the uterus, a fertilized egg can be fixed in other areas of the female reproductive system (for example, on the ovary or in the fallopian tube).
The percentage of ectopic pregnancies is very small, but the sad possibility always exists. When to suspect something is wrong? Severe increasing pain is the first signal of possible violations. In this case, the stomach hurts not from below, but from the left or right. Usually this is the place of improper fixation of the embryo. The pain intensifies when the doctor performs palpation. The most experienced specialists can even determine the place of implantation.
In our time, gentle methods have been developed to get rid of ectopic pregnancy. They do not give negative consequences and in the future do not interfere with motherhood.
Spontaneous abortion
A miscarriage is the rejection of a fetus that has already settled in the uterine cavity.. Many factors can provoke it. The main symptoms are bleeding or constant spotting, sharp pain and pulling sensations in the lower abdomen and lower back. The consequences depend on how quickly the woman herself and the doctors reacted.
It is important for expectant mothers to remember that mild pain is common in early pregnancy. “Guilty” is the same hormonal restructuring. The body adapts to the new state, and the lower back and lower abdomen “respond” to this.
Frozen pregnancy
In the gestation period of 3 weeks from the moment of conception, fading sometimes occurs. Then the test (both pharmacy and hCG) first confirms the pregnancy, and then as if it no longer “sees” it. However, menstruation does not occur. The detection of a missed pregnancy requires a careful approach and careful diagnosis.
Should I do an ultrasound?
In the normal course of pregnancy, ultrasound in the third obstetric week may be required to confirm that ovulation has occurred. Three weeks after conception, scanning during the normal course of pregnancy will be practically uninformative. The embryo will look like a small dot in the background of the uterine cavity.
ultrasound at 3 weeks pregnant
But if an ectopic pregnancy is suspected, it is precisely according to the results of ultrasound that the place of attachment of the embryo will become clear and a decision will be made on further actions. For greater reliability, ultrasound can be performed transvaginally, that is, through the vagina. The procedure is carried out carefully, gently and does not cause discomfort.
Will there be allocations?
For the third week of pregnancy, any special discharge is uncharacteristic. In obstetric counting, relatively thick and dense mucus can normally be released. It protects the egg from external infections - what if conception happens or has it already happened?
Strong mucous discharge, especially with an unpleasant odor, can be a signal of the disease. Better to check with a doctor.
When the fetus is fixed, slight implantation bleeding may occur. It's just a faint brown discharge or pink or bloody smears.
If the third week comes from conception, the pregnancy is confirmed, and suddenly the blood really started to flow, this may mean a miscarriage.
Body temperature: the line between normal and disease
If the embryonic period is three weeks, a slight increase in temperature (37.2 ° C) without signs of a cold is normal. However, 37.5 and more is already a danger signal.
When contacting a doctor, a woman must necessarily warn him about a possible or confirmed pregnancy. The doctor will take this into account when choosing treatment methods.
For many, a cold is a mild illness that can be treated on its own. Including antibiotics. For a pregnant woman, this is 100% unacceptable. Antibiotics, even topical ones, should only be prescribed by a doctor. And he can do this only in the most extreme and difficult cases. Side effects of this group of drugs can cause many different complications in the embryo.
3 weeks pregnant and sex
The third obstetric week will not do without sex. When planning a conception, a couple's intimate life usually follows a certain schedule. Ideally, sex should be on the day of ovulation, 2-3 days before and 2-3 days after it. This improves the quality of spermatozoa and increases the likelihood of conception.
In the third week after conception, the sex life of future parents may remain the same or change. Some women experience increased attraction to the father of the child. Others note a decrease in libido. Both are normal and should not cause concern.
There is also a rather rare sign of pregnancy, which almost never occurs. After intercourse, a woman may feel a sharp, severe pain in the vagina and on the labia. In this case, intimate life gives the expectant mother inconvenience, even a feeling of fear. Luckily, these feelings will pass soon.
If the intimate life of future parents threatens to deteriorate, it is important to take action in time. The main thing at this time is trust between a woman and her husband (partner). A man must be explained that there are changes in attraction, that he remains a loved and desired person. The future father will need patience and attention to his soul mate.
Intimate life will have to be stopped completely if there is a threat of miscarriage.
Nutrition of the expectant mother
- Eating is fractional, 4-5 times a day.
- For the full presence of protein, you need lean meat and, on the contrary, fatty fish (it contains important acids), as well as legumes and dairy products. Mushrooms are also protein, but such food can be difficult for the stomach.
- Fresh vegetables and fruits - to provide vitamins and minerals. No pharmaceutical vitamin complex will be truly effective if the mother does not receive natural vitamins from food.
- No colorful sodas! This is zero benefits and a large amount of calories.
- It is advisable to give up white buns and switch to coarse bread.
Another nutritional recommendation will help expectant mothers with early toxicosis. An attack of nausea can catch everywhere: at work, on a walk, in public transport. Sometimes it "rolls" so that the forces literally leave the woman. In addition, vomiting in public places is a strong psychological stress. What to do?
It is advisable to empirically find that “yummy” that will help suppress an attack of nausea. It could be anything. Bottle of soda mineral water it will save if the acidity of the stomach increases with nausea. Someone carries an apple in a plastic bag with them and bites off a little when nausea sets in. A piece of cheese, a cracker or something else can help - the expectant mother needs to carefully experiment.
In case of sudden vomiting, it is still better to carry a special bag and wet wipes in your purse.
Other Do's and Don'ts
A mother-to-be can and should take care of herself and her future baby. This should be done in all cases: if pregnancy is planned, allowed or has already been detected. The main recommendations are the same as in the first or second week:
- Taking vitamins. What kind of drugs are needed - the doctor must decide.
- If, for some reason, alcohol and cigarettes are still present in a woman's life, they need to be "driven" immediately and for a long time. In the third week from conception, any negative factors are dangerous for the embryo.
- Every effort must be made to avoid nervous shocks. Only positive emotions. But they should not be excessive either. Having experienced some kind of moral upsurge, the expectant mother may note with great surprise that she is very tired even from positive experiences.
- You can not lift weights and perform difficult physical work. If the expectant mother goes in for sports, the load will have to be reconsidered, or even completely change the type of activity. Most often, expectant mothers are recommended swimming (for their own pleasure) and yoga.
In the third week from conception, it is important for the expectant mother to remember: she is now not alone and shares with her baby everything that happens to her. Attention to yourself will make the third week of waiting joyful and happy.

Video guide: 3rd week of pregnancy: sensations, discharge, signs, fetal development
Pregnancy is a process in which a baby develops from two tiny parental cells. The development of the fetus by week of pregnancy is a fascinating story about what exactly happens in each week of pregnancy, how the weight and height of the fetus changes, what feelings a mother has as the pregnancy progresses. In the article we will talk about what interests every expectant mother: when the baby begins to hear her speech, when and how the weight of the fetus changes, when you can take a photo of the fetus with ultrasound, what causes mother's feelings during pregnancy and much more.
First and second weeks of pregnancy: baby? Which child?
photo: 1 week pregnantAt the time of the appearance of the embryo, the gestational age is already 2 weeks. Why? Let's decide what we will consider the term from. There are concepts of embryonic and obstetric period. Embryonic gestational age - the true period from the moment of conception. Obstetric period - from the first day of the last menstruation. The obstetric period is on average 2 weeks longer than the embryonic one. During an ultrasound, in the card of a pregnant woman, on the sick leave, the obstetric period will always be indicated by the date of the last menstruation. But from the third week of pregnancy, the development of the fetus actually begins. Below you will find a description of each week of pregnancy: how the fetus develops, what happens to the uterus, how the feelings of the expectant mother change.
3rd week of pregnancy: parents meeting
photo: 3 weeks pregnantAt the end of the second and beginning of the third week (on average, on the 14th day of the cycle), ovulation occurs. At this moment, the woman's egg leaves the ovary into the fallopian tube and where it meets with the sperm in the next day. Of the 75-900 million spermatozoa that enter the vagina, less than a thousand reach the cervical canal. And only one will penetrate the egg.
The spermatozoon and the egg cell carry half the set of chromosomes of the future person. As a result of their fusion, the first cell of a new organism with a complete chromosome set is formed - a zygote. Chromosomes determine the sex of the baby, the color of his eyes, and even the character. The zygote begins to divide and move to the uterine cavity. The journey to the uterus will take approximately 5 days, by which time the embryo will consist of approximately 100 cells. The next stage is implantation - the introduction of the embryo into the wall of the uterus.
4th week of pregnancy
photo: 4 weeks pregnantThe ball of cells is officially called an embryo. The size of the fetus at this time is like a poppy seed, approximately 1.5 mm.
At the end of this week, the expectant mother notices that the expected period does not begin. At this time, a woman may feel drowsiness, weakness, increased sensitivity of the mammary glands, mood swings. A pregnancy test shows a positive result. The test determines the hCG hormone, which begins to be produced after implantation.
The embryonic period lasts up to 12 weeks. There is a laying of the axial organs and tissues of the baby. A yolk sac is formed with a supply of nutrients, an amniotic sac, from these extra-embryonic organs, the fetal membranes and the chorion, the future placenta, subsequently develop. Below we will analyze what happens in the embryonic period every week, how the height and weight of the fetus changes, and what sensations a woman expects.
5th week of pregnancy
photo: 5 weeks pregnantThe embryo consists of three layers - the outer ectoderm, from which the ears, eyes, inner ear, connective tissue will form; endoderm, from which the intestines, bladder and lungs will develop; and mesoderm - the basis for the cardiovascular system, bones, muscles, kidneys, reproductive organs.
In the embryo, the anterior and posterior poles are determined - the future head and legs. The body of the embryo is laid along the axis of symmetry - the chord. All organs will be symmetrical. Some are paired, for example, kidneys. Others grow from symmetrical primordia, such as the heart and liver.
At the 5th week of pregnancy, with an hCG level of 500-1000 IU / l, it is possible to determine a fetal egg with a size of 2 mm, which is the size of a sesame seed. Each woman experiences this period differently, but most experience nausea, drowsiness, intolerance to odors - signs of toxicosis.
6th week of pregnancy
photo: 6 weeks pregnantNow the baby is no larger than lentils, at the beginning of the week 3 mm, and by the end - 6-7 mm. The embryo is somewhat similar to a fish and so far has little resemblance to a person. The rudiments of arms and legs appear. When the brushes appear, the legs will still be in the form of rudiments. The hemispheres of the brain are formed. A small heart pulsates, it is divided into sections.
From the villi of the chorion, the future placenta is laid, the vessels actively grow through which the exchange of blood takes place, and, accordingly, everything necessary for the unborn child between mother and baby.
At this time, the phenomenon of toxicosis may increase, severe weakness and vomiting may appear. It is important during these weeks of pregnancy to drink enough water.
7th week of pregnancy
photo: 7 weeks pregnantAn embryo about the size of a blueberry, height 8-11 mm, weight up to 1 g. There are hints of the future nose, eyes, ears and mouth. There is a fantastic growth rate of the brain - 100,000 cells per minute! Interdigital spaces have already appeared on the handles, but the fingers have not yet been separated. The umbilical cord and the uteroplacental circulation system are formed: the baby's breathing and nutrition comes from the mother's blood.
It is at this time that many expectant mothers often come for the first ultrasound during pregnancy. At 7-8 weeks with KTP (coccyx-parietal size) 10-15 mm. On ultrasound, a heartbeat with a frequency of 100 to 190 beats per minute is determined, which is much more than in an adult. At this time, the first photo of the gallery of fetal development is taken by week. Without instructions from a doctor and do not understand where to look. Later it will be clearer, especially on a three-dimensional ultrasound.
So far, the mother does not notice an increase in the abdomen, and the gynecologist can already say about the increase in the uterus. A woman has increased urination, which is associated with an increase in the volume of fluid in the body.
8th week of pregnancy
photo: 8 weeks pregnantThe baby is the size of a bean, from 15 to 40 mm, and weighs about 5 grams. Over the past two weeks, it has grown 4 times!
