2 week old embryo. Development of two fertilized eggs in the uterus
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.
2 weeks pregnant - what is this time? Surely almost every expectant mother thinks about it. How soon will the state of health, mood, figure change? Maybe it's time to change your lifestyle? All questions must be answered.
Points of view on the concept of "second week"
According to established practice, the doctor will count the gestational age from the beginning of the last menstruation. From the embryonic point of view, the counting starts from the middle of the cycle. This is the theoretical (but not exact!) time of ovulation.
There is also a third point of view - it can be called "purely feminine." Some future mothers count from the delay of menstruation. There is a certain logic in this. Sometimes pregnancy is not planned specifically, but it is allowed. In this case, the woman may not be aware of her new condition. Guess will come when there is a delay.
However, this approach can be very confusing. Therefore, it is better to consider pregnancy from the two most traditional points of view.
2 weeks: obstetric approach
From the point of view of doctors, the second week of pregnancy is only the preparation of the body for a possible conception. At this time, the next egg finally matures and ovulation occurs. If a woman plans to conceive, she carefully monitors this most important day of the monthly cycle. But there is no pregnancy itself from a medical point of view.
Embryonic method: everything has already taken place
If you count ovulation and the next few days as the first week of pregnancy, then the second week is a very important time. It is during this period that the fetal egg is fixed in the uterine cavity in order to begin its full development.
Is it time to run to the pharmacy?
From a medical point of view, there is no “interesting situation” in the second week. Now we need a test not for pregnancy, but for determining ovulation, it is sold in pharmacies. Daily measurements of basal temperature will also help calculate ovulation. They are carried out in the morning, at the same time, without getting out of bed. The thermometer is kept in the mouth, vagina or rectum. With ovulation, BBT rises slightly.
A pregnancy test in some cases can show an up-to-date result even a day or two before the expected menstruation. So that two weeks of embryonic age is a good time for the most impatient. It is important to follow some guidelines.
- Modern tests "work" at any time of the day. However, the morning result will be more accurate.
- A single test can be erroneous. Therefore, it is better to arrange 2-3 checks with an interval of 2-3 days.
- The optimal time for testing is, after all, not before the start of possible menstruation, but in the first days of the delay.
- After the test, you need to wait at least 10 minutes. It is not uncommon for one strip to be clearly visible immediately, and the second appears a little later.
- When buying a test in a pharmacy, you need to monitor its expiration date.
At a two-week embryonic period, a woman has a slightly increased level hCG(human chorionic gonadotropin). Therefore, a special blood test will show whether pregnancy has occurred or not. And also (very rarely) a particularly experienced gynecologist will feel an increase in the uterine cavity and determine pregnancy.
Feelings physical and psychological
During the period of ovulation, a woman is usually fine: menstrual pains have disappeared, the weakness associated with them and other unpleasant moments have disappeared. There are no specific sensations yet.
But two weeks after conception, many women already notice some signs:
- the sensitivity of the nipples increases, the chest swells;
- discomfort in the lower abdomen;
- the first signals of toxicosis of pregnant women (appetite disturbance, nausea -).
Often these experiences are more emotional in nature.. This happens in women who really want to get pregnant. How true sensations are true - it will become clear very soon.
Other signs and symptoms
Two weeks of embryonic gestation may be "marked" by some characteristic features. Arterial pressure at this time is usually lowered, urination is slightly more frequent. And sometimes taste preferences already present surprises. All these signs are easy to explain. Significant hormonal changes began in the body of the expectant mother. She brings some chaos into the usual life of a woman.
What will be the selections?
Mucous
When ovulation occurs (second week medically), vaginal discharge is like egg white. Two weeks after conception, slight transparent discharge without color and odor is considered the norm. They show that the hormonal restructuring of the body has begun and is proceeding normally.
Regardless of the method of calculating the term, there are very unpleasant discharges. They are white, viscous, often break up into flakes (they are called curdled). At the same time, itching or burning of the external genital organs is sometimes felt. Maybe it's thrush. But an accurate diagnosis and therapy is the doctor's concern. The gynecologist must be warned about the onset or possible pregnancy. Besides, both partners should be treated for confirmed thrush.
Bloody
During pregnancy, menstruation stops. According to the obstetric method, with these regular bleedings, everything is clear. The previous ones are over, the new ones will not start if the woman can conceive. In rare cases, the signal of ovulation is a slight bloody smear, which will leave a brown mark on the linen or pad.
If, according to the fetal count, the gestational age is 2 weeks, menstruation will not come. Often this is the first signal of a possible pregnancy for many women. At the moment of fixing the fertilized egg in the uterine cavity, the so-called implantation bleeding may appear. These are quite minor bloody issues. Many women consider them a signal of the upcoming menstruation, and only then, with a delay, they remember scanty smears.
Bleeding
L It is important for any woman to distinguish between scanty discharge and real bleeding.. When something like menstruation occurs at the wrong time, this is a very alarming signal. If there is no pregnancy yet, bleeding can be a sign of many gynecological diseases. In this case, see a doctor immediately. And the planned conception will have to be postponed for a while.
Moms take note!
Hello girls) I didn’t think that the problem of stretch marks would affect me, but I’ll write about it))) But I have nowhere to go, so I’m writing here: How did I get rid of stretch marks after childbirth? I will be very glad if my method helps you too ...
Also, bleeding can be normal menstruation. Then it becomes clear to the woman that conception did not occur.
There is also a third option. It is unpleasant to think about it, but it is a natural phenomenon. For a long time, doctors have established: fertilization of the egg is not pregnancy. It occurs at the moment of fixing the fetal egg in the uterine cavity. But for various reasons this may not happen. And then during menstruation, not only the unnecessary endometrium leaves, but also the dead fertilized egg. This phenomenon is not considered a miscarriage in the full sense of the word. After all, the potential embryo has not yet begun to develop.
Stomach ache
Preparation for ovulation (2nd medical week), sometimes accompanied by mild pain in the abdomen. They can be pulling. If the pain is mild, there is nothing to worry about.
If the stomach pulls in the second week of the embryonic period, this may be an alarm signal of fetal rejection. If conception was not specifically planned, many women attribute pain to the approach of menstruation. However, when planning a pregnancy, the expectant mother must definitely pay attention to such a sign and go to the doctor.
In rare cases, pulling pains in the abdomen can "respond" in the lower back. This is an individual feature and does not manifest itself in everyone.
The pregnancy has come. What does the fetus look like?
The medical method of calculation in this case is not affected. However, in the second week after conception, the concept of the fetus also does not apply. At this time we are talking about the embryo.
A real miracle happens in the body of the expectant mother. A single cell is fixed in the uterine cavity and begins to divide rapidly. A unicellular embryo becomes multicellular (the so-called morula). Very soon the most important systems future child's body.
ultrasound. Need or not?
If a woman is preparing for conception and is theoretically in the second week of pregnancy (according to the obstetric approach), Ultrasound will help in accurately determining ovulation. The specialist doctor will confirm that the follicle is ready to release a mature egg. Such a study is usually carried out in women with fertility problems.
In the second week after conception, ultrasound will still not be informative. It will only show the general readiness of the uterus to carry a pregnancy. If a photo is taken from the scanner at this time, the embryo will look like a tiny black dot.
ultrasound at 2 weeks pregnantBut you can jump ahead a bit and remember how some women count weeks after a delay. If two weeks have passed since that day, the obstetric period will be approximately six weeks, and the embryonic period will be four. And then the ultrasound will record how the tiny heart is already beating.
2nd week and intimate life
If a couple is planning a child, then where is it without sex? However, for successful conception, a careful approach is also needed here.
- It is advisable to give up intimacy 2-3 days before ovulation to improve the quality of spermatozoa;
- If ovulation is not specifically monitored, it is better not to protect yourself at all. After all, the egg may well mature earlier or later than the middle of the cycle;
- After intercourse, a woman is recommended to lie down for at least 15-20 minutes.
The physical and emotional component is very important. Conception should not take place against the background of ailments, problems and family conflicts. The child must be desired and expected!
And one more thing: no alcohol to “relax”. Neither expectant mother, nor father. Yes, possible nervous tension will go away and the mood will rise. And a real poison will enter the blood of potential parents. It may not harm the unborn child in any way, but it can cause serious damage.
An interesting fact: a little more than half a century ago, in the era of the USSR, it was enough for a woman to tell a doctor about an alcoholic conception in order to get a referral to terminate an unwanted pregnancy without any problems.
If a possible conception has already taken place, each couple decides for themselves the question of sex. Perhaps ovulation is delayed? Then the opportunity to become pregnant in a woman has not yet been realized. However, intimacy should not be too active and stormy. If conception has already occurred, it can hurt. The fact is that during orgasm, special hormones are produced that cause uterine contractions. If they are too strong, a woman's body can reject a fragile and unstable embryo.
If the temperature rises
A woman's overall body temperature may rise slightly for a variety of reasons. However, given the possible or upcoming "interesting situation", the temperature must be monitored. Its increase to 37.2 may be a sign of a cold that has begun. Even a mild illness can harm the unborn baby and requires treatment. Medicines should be allowed for pregnant women. It is permissible to use folk remedies.
- Complete nutrition. Vegetables, fruits, lean meats and, on the contrary, fatty fish. As well as dairy products;
- It's time to start taking vitamin preparations. They are prescribed by a doctor, taking into account the individual characteristics of each woman;
- Only positive emotions and no stress;
- Avoid passive smoking;
- No alcohol when planning and carrying a pregnancy;
- The expectant mother should not lift weights even for a short time.
It does not matter how exactly the weeks of pregnancy are counted. Preparing for conception and for bearing a child requires attention and caring attitude. And then in the life of the expectant mother very soon a special time will come.

In this 40 Weeks series, you'll learn what genetic research is for. And How chronic diseases may affect pregnancy.
Eye color, body structure and even mental abilities - all this is inherited. But a genetic disease can also be inherited. If you learn about possible problems at the planning stage, many of them can be solved. A number of diseases, such as hemophilia, spinal muscular dystrophy, or cystic fibrosis, can be passed on to a child even if neither parent shows signs of the disease. Genetic testing will help you make sure you have a healthy baby.

Hello girls! Today I will tell you how I managed to get in shape, lose 20 kilograms, and finally get rid of terrible complexes. fat people. I hope the information is useful to you!
How the fetus develops week by week is a real miracle. In just 38-40 calendar weeks, an embryo of several cells, similar to a bunch of grapes, becomes an infant with the most complex structure of the body. Immediately after giving birth, he begins to use a whole arsenal of skills and reflexes, quickly adapting to new living conditions. In our article - a brief description of the development of the child by day from the very moment of conception, a photo of the embryo and features of different months of pregnancy.
Human embryo in the first trimester
The first trimester is the most important and difficult stage in the development of the human embryo. It was at this time that the rudiments of its organs were laid, the nervous and other systems were formed. This period is associated with a large number of risks and requires the expectant mother to pay special attention to her health and lifestyle.
Embryo growth by weeks in 1 month of pregnancy
The first month is considered one of the most important and exciting for a reason, because right now a new life is born. At the beginning, his pregnancy has not actually occurred yet, but the body of the expectant mother is preparing for it by regulating hormonal background and functioning of the reproductive organs. All this is necessary not only for conception, but also for the normal implantation of the embryo in the uterus and the start of its development.
First trimester - start of pregnancy
1-2 weeks
From day 1 to day 14 of the new menstrual cycle, the follicle matures in the ovaries, from which the egg is released. It moves through the fallopian tube and meets with a sperm cell - one of almost 900 million that have entered the vagina. After fertilization, the morula embryo "descends" into the uterine cavity and the endometrium is implanted - approximately on the 12-17th day of the cycle. At this point, the actual pregnancy begins.
3 week
The fertilized egg continues to divide and grow into the wall of the uterus with shell cells. In parallel with this, the formation of the placenta and umbilical cord is launched - organs vital for the development of the fetus, through which it will receive nutrients. Now the embryo consists of more than 100 cells.
4 week
At this time, the first “jump” happens in the development of the child: the laying of all the systems of the future body of the baby begins. A particularly important stage is the formation of the neural tube, from which the brain and the entire nervous system are subsequently formed. The embryo grows to the size of a poppy seed less than 1.5 mm in diameter, from which time it is called an embryo. It is heavily implanted in the endometrium, which affects the level of the hCG hormone. It is at week 4 that a woman may notice a delay in menstruation and early signs of pregnancy.
Development of the human embryo at 4 weeks of gestation
Embryo development at 2 months
In the second month of pregnancy, every week the development of the fetus continues and is accompanied by significant changes in the structure of his body. During these 4 weeks, the umbilical cord, the neural tube, the rudiments of the limbs and fingers will form, the face will become even more proportional, the internal organs will differentiate.
5 week
The fifth week is the transition period between 1 and 2 months of pregnancy. Now the embryo has a conditional coccygeal-parietal size of up to 2.5 mm and a weight of about 0.4 g. The body systems are developing rapidly: the neural tube is improving, future parts of the brain, lungs, stomach, trachea are highlighted, blood vessels are growing.
6 week
The embryo grows from 3 to 6 mm, it looks like a fry, because. limbs are not yet developed. The placenta begins to form from the chorionic villi, hemispheres appear in the brain. The small heart, in which division into chambers takes place, is already contracting, driving out blood enriched with oxygen and nutrients for the construction of the body.
7 week
The embryo in this week of development has a length of 13-15 cm, more than half of the "growth" falls on the head. His body still has an arched shape, a "tail" is preserved on the pelvic part. On the upper limbs, which are ahead of the formation of the lower ones, a hand and fingers are drawn.
8 week
The size of the embryo increases to 20 mm - the baby grows almost 2 times in just a couple of weeks. He has a brain with two hemispheres and several departments, the beginnings of the lungs, the heart, the digestive system. The face is becoming more and more like a "human" - the eyes, ears, nose and lips covered with eyelids are perfectly distinguished.
Photo: what the embryo looks like at 8 weeks of gestation
How the fetus develops week by week at 3 months
At this stage in the development of the human embryo, its length doubles, and a third of the growth falls on the head. Gradually, the proportions will change, and now the baby begins to move his arms and legs, foci of ossification appear in the cartilaginous rudiments of the skeleton, the skin becomes less transparent, it is divided into layers in which the rudiments of hair follicles are formed.
9 week
The ninth week is the transition from the second to the third month of pregnancy. During this time, the development of the child by day will be accompanied by a rapid increase in growth from 22 mm at the beginning to 31 mm at the end. The baby's heart beats at a speed of 150 beats per minute, the musculoskeletal system is improving. The head of the embryo is tightly pressed to the chest and seems disproportionately large relative to the body and limbs.
10 week
By the end of this week, the baby will grow to 35-40 mm in KTR, most of the time he is in a half-bent state. The way the embryo looks also changes: the “tail” disappears, buttocks form in its place. The baby swims freely inside the uterus and, touching its walls, pushes off with his feet or hands.
11 week
In the brain of an embryo, more than 250,000 new neurons are formed every minute. The baby has the rudiments of milk teeth and nails. His limbs are bent, but the child regularly makes spontaneous movements with them, clenching and unclenching his fists. The iris forms in the eyes.
12 week
The most important event of this week of embryo development is the beginning of the active functioning of the placenta, which protects and nourishes the fetus. Thanks to her, the baby will receive air and all the necessary substances for growth and building his own body.
Embryo development towards the end of the first trimester
Stages of embryo development in the 2nd trimester
In the second trimester of pregnancy, all organs are already laid, they begin to grow and function. During this period, the development of the fetus is "directed" to the rapid growth and improvement of body systems.
How the embryo changes by day at 4 months
In the fourth month, the way the fetus looks is constantly changing: every day it looks more and more like a human embryo, the limbs are gradually lengthening, the head and torso will be more proportional by the middle of the trimester. The baby's organs are actively developing, forming different body systems.
13 week
This week of pregnancy is a transitional week between the first and second trimester, when, as a rule, the first scheduled screening is scheduled. It is necessary to assess the development of the embryo by day and exclude pathologies. By this time, the baby has a height of 6.5 to 8 cm and a weight of up to 14 g. The limbs, body and head become more proportional. The musculoskeletal system is being actively built, and there are already the rudiments of 20 teeth in the jaw.
14 week
Now the baby is completely fed through the placenta and umbilical cord. It grows up to 8-9 cm, a chin and cheeks are drawn on its face, the first colorless hairs appear on its head. The kidneys begin to excrete urine amniotic fluid. In girls, the ovaries move into the pelvis; in boys, the formation of the prostate gland begins.
15 week
What does the fetus look like at 99-105 days of development? Its proportions approach normal, KTR increases to 10 cm, and weight - up to 70-75 g. All parts of the face are formed, eyebrows and eyelids can be distinguished, the auricles acquire a characteristic shape and relief.
16 week
The KTR of the baby reaches almost 12 cm, and the weight is 100 g by the end of the week. The development of the embryo by day at this period is impressive: all organs have already been formed in it, the heart and kidneys are actively working. The structure of the facial muscles is improved, due to which the child begins to grimace.
Baby after 16 weeks of pregnancy
Pregnancy at 5 months: how the embryo develops by day
At the 5th month, the baby is growing rapidly, all his organs are gradually included in the work, various systems of the body are being improved and coordinated. In particular, the movements of the baby become more coordinated, and due to the increased weight of the fetus, the expectant mother will be able to feel the first movements.
17 week
The fetus grows up to 12 cm in KTR and already weighs about 140 g. This week, the baby’s own immunity comes into play, which, together with the placenta, will protect him from negative impact external factors. Thin skin is covered with original lubrication, subcutaneous fat begins to accumulate under it.
18 week
By the beginning of the week, the KTR of the baby is more than 14 cm, and the weight is from 140 to 200 g. How does the fetus develop by day? First of all, its proportions change: the limbs grow faster than the head. The hearing aid is active, the child reacts to sharp and loud sounds. The structure of the brain becomes more complex, the transmission of nerve impulses improves, due to which movements become more coordinated.
19 week
The CTE of the fetus increases from 15.3 to 19-20 cm, the average weight is 240 g. The baby's skin is covered with lanugo fluff. The bronchial tree grows. The sex and thyroid glands begin to produce hormones. The whole body is protected by a thick primordial lubricant.
20 week
The development of the fetus on the days of this week is associated with changes in its appearance and coordinated work. different systems his body. The skin of the baby due to lanugo and the gradual accumulation of subcutaneous fat becomes less transparent. More than 25 liters of blood per day passes through the heart.
Fetal development by week at 5 months
6 month: how does the human embryo change?
In the sixth month, the structure of the baby's brain improves. The length of the body and limbs and the size of the head become proportional, and the appearance is generally the same as that of a newborn. Interestingly, by this time the child already has a unique pattern on the fingertips.
21 weeks
By the end of this week, the baby grows to 26.7 cm and weighs about 300 g. His movements are clearly felt, and the movements of the child's day can be traced. What changes occur in the development of the fetus? Its digestive and excretory systems are trained, acid appears in the stomach, taste perception is improved.
22 week
The KTR of the child increases to 28 cm, the weight is already more than 400 g. The volume of subcutaneous fat increases, due to which the fetus every day becomes more and more like a newborn. Due to the rapid development of the brain and nervous system the baby begins to "study" the surrounding space - pulls the umbilical cord, evaluates the taste of amniotic fluid, reacts to changes in light and different sounds.
23 week
The growth of the baby from the heels to the top of the head exceeds 29 cm, the weight reaches 500 g. How does the fetus develop this week? Since the second month, his brain has increased 40 times, reactions to stimuli and movements become logical and coordinated. According to some studies, the child begins to dream.
24 week
At this time, the baby grows to 30-32 cm and weighs about 530 g. A surfactant lubricant appears in the lungs, which is necessary for breathing protection. The cerebral cortex is covered with new grooves and convolutions. Subcutaneous fat accumulates more actively.
What does a fetus look like at 6 completed months?
The position and development of the fetus at 7 months
In the last month of the second trimester, the baby's skin smoothes out, becomes denser and gradually acquires a lighter shade. Under it, subcutaneous fat is accumulating faster and faster, which is vital for normal thermoregulation. The child often opens his eyelids, studying the surrounding space and reacting to bright light.
25 week
Height from crown to heels is about 34.5 cm, and weight increases to 700 g. Facial features are fully formed. The bone marrow takes over the function of hematopoiesis. The lungs develop alveoli - bubbles that will open after the first breath of the child.
26 week
At this stage, the size of the fetus by day changes a little more slowly than in previous months. The height of the baby is about 35 cm, and the weight is 760-850 g. All systems of his body are “training” and preparing to work outside the womb. Thanks to the coordinated work of the brain and the adrenal cortex, the synthesis of new hormones begins.
27 week
By this time, the child adds another 1 cm in height and already weighs about 900 g. He gradually accumulates subcutaneous fatty tissue. Hair on the head, eyelashes and eyebrows may become slightly darker. The organism becomes more and more viable, i.e. even in the case of premature birth, the chances of saving the life and health of the baby increase.
28 week
The development of the child by the end of the 7th month allows him to survive even outside the womb in the absence of pathologies in the structure of the organs. He gains enough subcutaneous fat, although for normal independent thermoregulation, its volume must increase significantly. At this time, the hemispheres of the brain work more actively, it is already known whether the baby will be right-handed or left-handed.
After 7 months, the baby begins to gain subcutaneous fat
Embryo development by week in the 3rd trimester
The last trimester of pregnancy is the time of active accumulation of subcutaneous fat, improvement and coordination of the work of body systems. All this is necessary to prepare the child for childbirth and life outside the mother's womb. How does the fetus develop by week?
fetus at 8 months pregnant
In the eighth month, the baby quickly gains weight and continues to grow. His skeletal and muscular systems are getting stronger. The lungs are preparing for breathing, the diaphragm is constantly “training”. The brain is already fully formed, but its structure and functioning are constantly being improved.
29 week
There is less and less space in the uterus, because the child grows up to 38 cm in height and already weighs more than 1 kg. Because of this, his tremors become more noticeable and can cause discomfort for the expectant mother. All systems of his body are actively working, in particular, the kidneys excrete almost 500 ml of urine per day into the amniotic fluid.
30 week
How does the fetus develop by day? First of all, he very quickly accumulates subcutaneous fat, due to which his weight increases to 1.3 kg. The skeletal system is getting stronger, the limbs are lengthening, the growth from the crown to the heels is more than 39 cm. The skin brightens, the folds are gradually smoothed out. In the lungs, a protective lubricant-surfactant is actively produced.
31 weeks
This week, the child already weighs more than 1.5 kg and grows up to 40 cm. By his activity, you can track his sleep and wakefulness, as well as reactions to external conditions - noise, bright light, lack of fresh air, uncomfortable posture of the mother. The eyes are fully formed, the color of the iris is the same for most babies, it will change after birth for three years.
32 week
The height of the child is 42 cm, weight is about 1.7-1.8 kg. The development of the fetus by day is aimed at preparing his body for independent functioning. For this, the recruitment of subcutaneous tissue is accelerated, respiratory and sucking reflexes are constantly trained, digestion and blood supply are improved. The work of the excretory, nervous and endocrine systems becomes more complicated.
Fetal development at 8 months: the baby is already like a newborn
9 month: how does the baby look and develop?
The ninth month of pregnancy is considered by many to be the “finish line”. Indeed, the development of the child by this time makes him viable: the baby will already be able to suck milk on his own, and the risks of problems with breathing and thermoregulation are decreasing every day.
33 week
The child grows up to 44 cm and already weighs about 2 kg. It becomes crowded, because of which even weak movements are clearly felt. At this time, the baby takes the final position in the uterus - head or feet down. At week 33, the size of the heart increases, the tone of the blood vessels increases, the formation of alveoli in the lungs is almost completed.
34 week
The growth of the baby increases by another 1 cm, while the weight gain due to the set of subcutaneous fat can be almost 500 g. The musculoskeletal system of the baby is strengthened. The bones of the skull are still soft and mobile - this is necessary for passage through the birth canal. Hair on the head grows faster and can change color.
35 week
On average, height from heels to crown is 45 cm, and weight is from 2.2 to 2.7 kg. The child looks well-fed and every day accumulates more and more subcutaneous fat. On his fingers, the nail plates are clearly visible, the vellus hair-lanugo becomes a little less.
36 week
The height and weight of babies at this time can vary over a wide range. The body length is from 46 to 48 cm, and the weight is from 2 to 3 kg. The skin of the child becomes smooth and bright, the number of folds decreases. All his organs are ready to work, and the body becomes completely viable.
Development of the child by the end of 9 months: the baby is ready for birth
Child development in the last weeks of pregnancy
The 10th month of pregnancy is an exciting time: childbirth can begin any day. The development of the child by this time makes him fully viable, there are no longer any risks to his health during delivery.
37 week
The baby grows up to 49 cm. Every day he adds about 14 g. His appearance before childbirth will not change. The cartilages in the nose and on the auricles gradually get stronger. The lungs are ripe, the alveoli, protected by a surfactant lubricant, are ready for the first breath. The intestine performs periodic contractions to prepare for full peristalsis.
38 week
The fetus looks exactly like a newborn. His body is fully formed and ready to function. The baby takes the final position in the uterus and rests his head against its base. The bones of the skull are still mobile: thanks to this, the child will be able to pass through the birth canal.
39 week
The baby gains 20-25 g per knock, his height can vary from 50 to 55 cm. He "falls" into the pelvis and begins to put pressure on his bones. The limbs, the length of the body and the size of the head are completely proportional. All sense organs are well developed.
40 week
The development of the fetus by this time is completed - it is ready for birth, has all the necessary reflexes to maintain health and nutrition. This week, the placenta gradually ages, and hormonal changes in the woman's body trigger the natural process of childbirth.

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. In this case, it is better if the daily diet is 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 of these substances are contained in sufficient quantities in cottage cheese, fish, broccoli, apples, fresh vegetables and fruits, as well as in bread. coarse grinding. 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, there is an active intrauterine development baby. 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. Appearance 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. Indeed, starting from the first hours of conception, the fetal egg has a developed consciousness.
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
In order to maintain a pregnancy, it is necessary to follow the drinking regimen, 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 are taking place in her body that will make her life of motherhood happy nine months later.
Symptoms of pregnancy in the third week

change in taste preferences;
3 WEEK PREGNANT
This week can be considered the beginning 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.
Videos 3 weeks pregnant
Sources: No comments yet!
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 construction 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 terminate an unwanted pregnancy, then 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 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.
