At what month of pregnancy does the belly become visible. At what month of pregnancy does the tummy appear in the expectant mother

Thoughts about pregnancy often lead to the appearance in the subconscious of a picture depicting a future mother with a big belly, where the baby is comfortably located. Having decided to give birth to a second child, every woman is puzzled by how much earlier than the first time, she will begin to corresponding changes in appearance, and when the belly begins to grow during the second pregnancy.

What explains the interest of a woman in the volume of her abdomen?

These questions arise for several reasons:

1. It is interesting when others find out about a woman's pregnancy.
2. By the time the tummy appeared, one can judge whether the pregnancy is proceeding normally.
3. Some, by the size and shape of the abdomen, hope to find out the sex of the unborn child.
4. Every woman wants to know at least roughly what month she will need special clothes for.

General features of bearing a second child

All this is very important for the expectant mother. You should figure out what exactly affects the period when the belly begins to grow during the second pregnancy.

Photos of women awaiting the long-awaited birth of a baby and who are at the same time show differences in volumes. During the first pregnancy, an increase in the abdomen occurs on average at the 16-18th week. Slender lovers of tight-fitting clothes are "declassified" immediately. But others may not be aware of changes in the position of a magnificent woman until she goes on maternity leave, that is, almost until the 25th week. It turns out: despite the fact that the uterus increases in everyone according to the same laws, outwardly this manifests itself in different ways.

Why is the belly bigger the second time?

There are several more reasons that affect the increase in the circumference of the abdomen and, as a result, the change in the appearance of a woman:

Anatomical specifics of a woman giving birth again

All of the above is fair and objective. And yet, the scenarios for the development of the first and second pregnancy are different. The first childbirth brings irreversible changes to the female body. This fact allows us to identify the reasons that affect the change in the circumference of the woman's abdomen.

Wanting to know when the belly begins to grow during the second pregnancy, you should not take into account the reviews of mothers who have already given birth again. As well as when carrying the first child, for each pregnant woman, the timing of the appearance of the tummy can vary significantly. However, mostly during the second pregnancy, the belly will become noticeable earlier by about 4-6 weeks, that is, others will be able to enjoy the changed position of the woman a month faster.

The reason for this is that the uterus does not return to its original state after the first birth, which is quite normal. Therefore, in thin women, the tummy will begin to be visible at 12 weeks. And let friends and relatives vied with each other about the gender of the baby to be born!

Location of the uterus

In addition, it is impossible to say unequivocally when the belly begins to grow during the second pregnancy (a photo by week helps to see a noticeable difference in the increase in volumes) is impossible.

But changes in the position of the abdomen will certainly affect the timing. The uterus will now be located much lower than in the first pregnancy. As mentioned above, during the first pregnancy, the muscles of the pelvic floor, abdominal wall and ligaments were severely "suffered" before and during the first birth, and they no longer hold the stomach so cheerfully. On the one hand, this alleviates the situation of the pregnant woman: she is less bothered by heartburn, nothing makes breathing difficult. On the other hand, the lower spine and pelvic bones suffer. A bandage can help here, which you can buy only on specialized sites or in a pharmacy. And only the one recommended by the doctor.

Everyone is different: reviews of pregnant women

When the belly begins to grow during the second pregnancy (reviews from women can be an invaluable source of information), many also note differences in the shape of the abdomen. On the forums they write that, basically, for the owners of a narrow pelvis for the second time, it sags more and looks gentle, and it drops much later. This discourages those who like to tell fortunes on the sex of the child according to the shape of the abdomen. None of them can assume that it is not a girl, but, on the contrary, a male baby that comfortably develops in a rounded belly that greatly increases the mother's waist.

Moms themselves claim that it is more difficult for them, pregnant for the second time, to hide their position, since the belly becomes noticeable earlier than the first time. This is confirmed by the women themselves. They admit that when the belly begins to grow during pregnancy, the second baby becomes the object of congratulations earlier for a whole month.

Negative experience from a previous pregnancy

It happens that the previous gestation of the fetus is interrupted, and the woman fails to give birth to a baby. It is no coincidence that, worrying about the current baby, the mother, being in the early stages, will look forward to changes in her own appearance, and at the next appointment with the doctor she will ask when the stomach begins to grow during the second pregnancy after a miscarriage. Usually, there are no differences in the volume and timing of the appearance of the abdomen, depending on the outcome of previous pregnancies.

Mandatory trips to the gynecologist

Women try to calculate when the belly begins to grow during the second pregnancy. And not always their desires are connected with the desire to find out the sex of the child or to acquire appropriate clothes in time. The doctor is very interested in this information, whose attention pregnant women should in no case be neglected. To give birth to a healthy baby, you need to regularly visit the gynecologist leading the pregnancy, where he will feel the tummy, measure it with a tape and a special device.

And all the above signs will help him not in guessing the sex of the child, but in deciding how the pregnancy is proceeding, whether there are reasons for concern and a threat to the baby. It was the first time and it will be so in all subsequent pregnancies. Every mother, regardless of whether this happens for the first or second time, should go through this period under the supervision of a doctor: take tests on time, observe a diet and physical activity.

A few words at the end

If the changes that occur with the uterus comply with accepted standards, neither the size nor the shape of the abdomen will in any way affect the health of the mother and her baby, and even more so will in no way affect his gender.

For parents looking forward to the birth of a baby, it does not matter at all whether it will be a girl or a boy. And when the belly begins to grow during the second pregnancy with twins, there is definitely no limit to the happiness of expectant mothers and fathers. By the way, this happens quite early, and it will not be difficult to guess why. And yet, the main thing for parents is to help every baby be born healthy and on time.

Expecting a baby for women is one of the most tremulous periods. Any information matters, such as the degree of uterine enlargement and visualization of pregnancy. Changes depend on the characteristics of the body, the weight of the expectant mother and other things. In addition, it matters whether a woman has given birth before.

At what week does the growth of the abdomen begin during the first pregnancy

While waiting for the birth of a baby, the belly of a pregnant girl increases due to several factors:

• amniotic fluid content;
• fetal development;
• uterus growth.

At what time does the belly start to grow? This is a very delicate matter. For some women, it increases already in the first months, while others manage to hide the fact that they are preparing for the birth of a child for a long period. Gynecologists believe that the belly should be visible after the 16th week of pregnancy. If the ultrasound has identified twins, then roundness may begin to appear 3-4 weeks earlier.

A woman who is preparing to become a mother for the first time may develop a belly much later than those who are going to give birth to a second child. The size increases longer due to the muscles that actively resist stretching. In addition, the growth rate of the abdomen may depend on other factors. Sometimes it becomes noticeable that a woman is going to become a mother, only in the later stages. Muscle stretching occurs much faster in those who have already gone through childbirth.

When does the belly start to grow in pregnant twins?

Another question of interest to expectant mothers concerns multiple pregnancies. Noticeable roundness, if two fetal eggs were visible in the ultrasound photo, appears earlier. In this case, the volume of amniotic fluid increases faster, so the changes occur about a month earlier. Pregnant women already in the third trimester have a tummy that is visible to the naked eye.

The uterus during multiple pregnancy increases a few weeks earlier than when carrying a single child. The total body weight of the mother is also growing faster. However, a large belly is not necessarily evidence that a woman will have twins. Sometimes this is a sign of an incorrect calculation of the timing of pregnancy, a large fetus, or the formation of amniotic fluid in a significant amount. The position of the future baby also matters.

At what time does the belly begin to grow during the second pregnancy

It is believed that the child of a mother who became pregnant a second time is slightly larger. The size of the tummy matches this. Doctors confirm this fact. The fetus during the second pregnancy grows in height and gains up to 500 grams more weight than while waiting for the first child. The skin with muscles is stretched faster, the navel is twisted, already for a period of four months, the roundness is clearly visible.

The growth of the uterus in each woman is individual. If the waiting period for the first child remains invisible to others for a long time, then the second pregnancy becomes visible earlier. The abdominal muscles after the first birth are already stretched, so the process goes faster. It is important to consider the physiology of the future mother, especially the structure of the pelvic bones. An expectant mother with a narrow pelvis “rounds” faster during pregnancy than women with a wide skeleton.

At what stage of pregnancy does the belly start to grow? Until the tenth week, visual changes may not occur. After that, a slight roundness appears, growing every day. The most active period of fetal development begins from the thirteenth week. After the first pregnancy, the wall of the abdominal muscle is no longer as elastic as before, so it may seem that the "interesting position" appears visually faster.

For every woman, becoming a mother is a huge change in her life. Therefore, they want to know everything about this, especially how the fetus should develop correctly, in what month does the belly appear in pregnant women? These questions are asked quite often, especially by those who are preparing to become a mother for the first time.

First, let's explain the definition of "tummy". In the first months of pregnancy, a woman's belly may grow, the reason for this is malnutrition or gas formation. In these first months, the uterus is not yet enlarged.

Pregnant women have a moment when they begin to think: “at what time does the stomach begin to grow?”. Let's try to answer this question. The uterus begins its growth only at 16 weeks from the moment of conception. Therefore, the belly will be visible to other people only at the 20th week of pregnancy. If a woman goes in for sports, i.e. if she has a developed press, then the tummy will become visible much later.
Also, the appearance of the tummy depends on which pelvis the pregnant woman has. In the event that the expectant mother's pelvis is wide enough, then her tummy will become visible only by the 4-5th month of pregnancy. In obese women, it will be possible to notice the “position” even later. In women who give birth for the second time, the belly may appear earlier. The number of embryos can also affect the size of the abdomen, namely, increase it. This is the only thing that can really affect the month in which the belly appears in pregnant women. If the expectant mother has triplets or twins, then the belly can be noticeable already in the first 3 months.

In general, the answer to the question of what week of pregnancy the belly begins to grow will be as follows. If a woman has one fetus and its development is going well, then the stomach should appear only at the 12th week of pregnancy. Already at week 16, your tummy will become noticeable not only to you.
And by the 27th week of pregnancy, the question is - at what time does the stomach begin to grow? - will not be relevant, because by this time it will be impossible to hide your baby under blouses and other clothes.
At the same time, the expectant mother should be interested not only in how long the belly begins to grow, but also in how her baby should develop correctly.
On the 8th - 10th week of pregnancy, the fetal egg reaches a diameter of 22 mm.
At the time when it is necessary to register, namely, by 12 weeks, the length of the fetus will be seven centimeters, and its weight will reach 20-25 grams. At this time, having come to the ultrasound, you can see that the fetal egg almost completely filled the uterine cavity.

By the 17th week of pregnancy, the fetus will reach a length of 12 cm, while its body weight will increase to 100 grams. By this time, the question of how long the stomach begins to grow disappears by itself, since all the excitement associated with it is already behind. The tummy has noticeably grown and rounded.

By week 20, the length of the fetus will reach 25 cm with a weight of about 300 g. At 24 weeks, your baby will have time to grow significantly. By this time, its length will be almost 30 cm, and the weight will vary from 600 to 700 grams.

By week 28, the length of the fetus, as a rule, is 35 cm with a body weight of about 1.0-1.2 kg. At the 32nd week, body weight will increase to 1.5 kg with a fetus length of 40 cm.
At week 36, the baby is practically formed, and by this time his indicators will be as follows: weight - 2.5 kg, and length - about 48 cm.

However, it is impossible to say that these indicators are the same for everyone. They are quite individual, because the baby in the womb of each mother is formed in its own way. Therefore, the above data is very average, and your baby may reach large sizes or be slightly smaller due to individual characteristics.
The body weight of the fetus by the date of delivery, as a rule, is 2.6-5.0 kg, and its length can reach 54 cm.

Thus, it should be important for the expectant mother: to bear the child for the entire required period and provide him with everything necessary for proper growth and nutrition, and the tummy and its size are not the most important thing.

Features of the growth of the tummy

Often, expectant mothers confuse the concept of "abdominal growth" and "uterine growth", because the actual belly can increase for reasons independent of pregnancy: overweight, overeating, and active growth of the uterus begins at 16 weeks, so a truly "pregnant" tummy begins to appear from 20 weeks of childbearing.

Many women want to know at what month of pregnancy the belly appears also in order to navigate the wardrobe update. After all, girls always want to look beautiful and well-groomed, regardless of the state of pregnancy.

In addition, the growth of the tummy is a variable value that can change throughout the day, depending on the degree of saturation of the woman, the presence of fat, the amount of amniotic fluid and other factors. In addition, an early manifested belly is not always a reason for pride, since it may indicate certain problems with the tone of the uterus. Moreover, the rapid growth of the belly can provoke the appearance of stretch marks.

What affects the size of the tummy?

It is not possible to determine exactly when a tummy will appear in a particular pregnant woman. However, there are a number of factors that somehow affect the degree of growth of the belly.

1. Priority: it is believed that during the first pregnancy, the tummy does not grow as fast as during subsequent ones. This is explained by the non-stretching of the muscles of the abdominal cavity. The second and next pregnancies are marked by big tummies precisely because the muscles have already undergone deformations and are easier to re-experience.

2. Features of physique and anatomy. So, women with a narrow pelvis can boast of a rapidly growing tummy. This is because the uterus can only grow forward, and not be located inside the pelvis. In addition, it is easy to explain at what month of pregnancy a belly appears in thin women: no doubt they will become the owner of a noticeable tummy earlier than the rest.

Since the pre-pregnant physique plays an important role in determining the rate of growth of the abdomen, it is quite simple to determine in which month of pregnancy the belly appears in full ones. As a rule, fullness is accompanied by the presence of a wide pelvis, the child is placed there and the growth of the uterus becomes noticeable much later. In addition, the overall large physique of a woman hides a growing tummy for a long time.

3. Location of the child. If the child is located closer to the back wall of the uterus, then the tummy grows more slowly and is not so noticeable until 6 months.

4. The size of the unborn child and the number of babies in the uterus. Of course, a large baby in the tummy will be much more noticeable than a small one. Many experts, determining at what month of pregnancy the belly appears with twins, agree that the belly during such a pregnancy from the 11th week ceases to look like a singleton pregnancy. The rapid growth of babies increases the belly by 28 weeks to almost the size of the prenatal belly of a normal pregnancy. By 32 weeks, the belly of a woman pregnant with twins reaches its maximum size.

However, experts note that with any options for the growth rate of the abdomen in pregnant women, the main thing is the harmonious development of the fetus and the mother's care for the unborn baby. In order to avoid problems with bearing, to alleviate the severity of wearing an already grown tummy, it is advised to use a bandage in the last third of pregnancy and follow the diet.

Nine months pass from conception to birth. A woman who is preparing to become a mother for the first time wants to know at what month of pregnancy her belly begins to grow. It should be noted right away that this is a very individual phenomenon. There is no clear evidence for this. In some women, the belly becomes noticeable at a very early date, while in others only at the end of the gestation of the embryo. The size of the belly of a pregnant woman is influenced by various factors - from physiological and anatomical features to the physical condition of the muscle mass of the whole body.

embryo development

The individual development of any living organism has a continuous process, starting from the moment of conception and continuing until death. Embryonic development begins from the moment of fertilization of the egg, the formation of a multicellular organism and ends with the release of the “ripe” fetus from the embryonic membrane.

During this period, all internal organs of vital systems are formed in the embryo. During this time, great changes occur in the female body. First of all, the hormones progesterone and prolactin are connected. All internal organs and systems undergo a kind of “reconfiguration”. The increased load on the bone, endocrine, circulatory, digestive, urinary and nervous systems, as well as on the ligamentous-tendon apparatus, undergoes a serious transformation of the entire woman's body during this period.

First of all, during pregnancy, the mammary glands change their shape, their size changes, they prepare for the lactation period. The birth canal becomes softer and more elastic. This is necessary for the normal movement of the embryo through the birth canal. However, the most important organ that plays a role throughout embryonic development is the uterus. Its growth is directly related to the growth of the fetus inside. The uterus itself becomes heavier due to the growth of the placenta. This is a special "building material" that provides a direct link between the embryo and the mother's body. Moreover, between the placenta and the walls of the uterus, the required amount of a specific fluid - amniotic fluid - gradually accumulates. Through them, there is an intensive intake of nutrients from the mother's body, and the metabolic products of the embryo are excreted.

There are extremely clear limits on the size of the fetus at each new stage of development. In cases where deviations from normal sizes are observed, the alarm should be sounded, since pregnancy can go into a "frozen" form. It is not possible for a woman to track such a condition on her own, therefore, constant monitoring by a gynecologist throughout the pregnancy is necessary.

The weight of the uterus in a woman in the normal state, when there is no fact of pregnancy, does not exceed 100 grams. When carrying an embryo, the weight of the uterus increases to 1 kilogram. This is due to the increase and thickening of the uterine walls. Of course, the blood supply increases significantly and the vessels of the uterus grow. The appearance in the uterus of a new organ - the placenta, which directly connects the mother's body with the embryo - also significantly increases the mass of amniotic tissues. The mass of the placenta can be up to 800 grams. The volume of amniotic fluid that performs various vital functions for the embryo can range from 800 to 1000 milliliters.

In a normal pregnancy, by the end of the third month, the uterus expands to the upper edge of the womb. Through the anterior wall of the peritoneum at this time, the uterus is easily palpable during normal palpation.

Factors affecting the growth of the abdomen

In cases where the pregnancy is the first, many women notice a rounding of the abdomen at the sixteenth week. From the side of pregnancy is not very noticeable. During the second pregnancy, the belly becomes noticeable much earlier. This is caused by a previous pregnancy, in which the muscles of the uterus and abdominal cavity were already in a state of prolonged stretching.

If a woman has a somewhat narrowed pelvis, then the stomach becomes visible a little earlier. Due to anatomical features, the uterus is not able to expand proportionally to the sides, so it rises above the pubic area. In thin girls, pregnancy is noticeable earlier than in full ones. If a woman is pregnant with twins, her belly becomes noticeable from the beginning of the third month.

The height and weight of a woman are also determining factors for an increase in the abdomen. Some women find themselves consuming more food and fluids from the moment they conceive.

Girls involved in sports have an elastic muscular corset in the peritoneum, so the growing belly will be felt by the expectant mother herself and felt by others a little later.

The location of the fetus in close proximity to the spinal column will not give out a pregnancy a little longer than the generally accepted terms.

One of the important factors, as usual, can be heredity, both of the mother and the unborn child. If the baby is large, it will accelerate the rounding of the mother's abdomen.

In any case, every pregnancy, even in the same woman, is a very individual condition, the course of which is not easy to predict even for an experienced obstetrician.

How to measure the circumference of the abdomen at different stages of pregnancy

From the beginning of the twentieth week of pregnancy in the antenatal clinic, the observing obstetrician will take regular measurements of the circumference of the abdomen. When the uterus drops down on the eve of childbirth, this will be a clear signal that you are ready to take birth soon. Every organism is an individual. That is why even in the same woman, with each new pregnancy, the size of the abdomen can be different. The increase in the size of the abdomen relative to the gestational age is shown in detail in Table 1.

Table No. 1. Terms of pregnancy and the corresponding increase in the size of the circumference of the abdomen.

The size of the baby in different periods of embryonic development

During the conception period, a miracle happens - two cells belonging to opposite-sex parents join together, and an embryo begins to form, which, after nine long months, will be born, inheriting the genetic characteristics of dad and mom. At the time of the appearance of the embryo, the gestational age is two weeks. The growth of the embryo in the walls of the uterus begins from the fourth week after conception. At this point, the woman notes that she does not have a period. This period may also be accompanied by some not very pleasant conditions:

• increased drowsiness;
• mood variability;
• increased sensitivity of the mammary glands;
• weakness and unwillingness to actively move;
• excessive worry.

Starting from the fourth week of embryonic development, we can talk about the growth and weight of the embryo, followed by the formation of internal organs and tissues. Approximate indicators of height and weight with the onset of each new week of pregnancy are shown in table No. 2.

Table number 2. Embryo development by week with height and weight.

gestation of twins

When carrying twins, the overall picture changes significantly. Rounding of the abdomen can already be observed in the first trimester of pregnancy. Thus, the uterus begins to expand four weeks earlier. The weight gain is also more significant.

In multiple pregnancies, the placental tissue has a larger mass compared to singleton pregnancies. Obstetricians testify that in cases of the birth of twins, delivery begins somewhat earlier than the indicated dates. Such women are at risk, so they are prescribed more frequent gynecological examinations. An experienced doctor can accurately diagnose twins from the twelfth week. The uterus during this period is already doubled in comparison with the uterus of a woman pregnant with one fetus.

Of great importance during pregnancy at any time is the clothes that the expectant mother puts on. First of all, it should not be tight, tight-fitting, squeezing, creating even the slightest discomfort. The baby is very vulnerable in the womb, he perfectly feels any changes that occur in a woman's life - from the position taken in a dream to clothing items. Synthetic fabrics, from which most of the underwear is made in the modern world, can also harm the mother and unborn child, disrupting the processes of thermoregulation and the work of the sweat glands.

For every woman, becoming a mother is a huge change in her life. Therefore, they want to know everything about it, especially how the fetus should develop correctly in pregnant women? These questions are asked quite often, especially by those who are preparing to become a mother for the first time.

First, let's explain the definition of "tummy". On a woman, her stomach may grow, the reason for this is malnutrition or gas formation. In these first months, the uterus is not yet enlarged.

Pregnant women have a moment when they begin to think: “at what time does the stomach begin to grow?”. Let's try to answer this question. The uterus begins its growth only at 16 weeks from the moment of conception. Therefore, the belly will be visible to other people only on. If a woman goes in for sports, i.e. if she has a developed press, then the tummy will become visible much later.
Also, the appearance of the tummy depends on which pelvis the pregnant woman has. In the event that the expectant mother's pelvis is wide enough, then her tummy will become visible only by the 4-5th month of pregnancy. In obese women, it will be possible to notice the “position” even later. In women who give birth for the second time, the belly may appear earlier. The number of embryos can also affect the size of the abdomen, namely, increase it. This is the only thing that can really affect the month in which the belly appears in pregnant women. If the expectant mother has triplets or twins, then the belly can be noticeable already in the first 3 months.

In general, the answer to the question of what week of pregnancy the belly begins to grow will be as follows. If a woman has one fetus and its development is going well, then the stomach should appear only at the 12th week of pregnancy. Already at week 16, your tummy will become noticeable not only to you.
And to the question - at what time does the stomach begin to grow? - will not be relevant, because by this time it will be impossible to hide your baby under blouses and other clothes.
At the same time, the expectant mother should be interested not only in how long the belly begins to grow, but also in how her baby should develop correctly.
