As the saying goes, you can hide three things but not four. In other words, in most cases, women can’t see their belly when they are 3 months pregnant, but they can definitely see it after 4 months of pregnancy. Of course, this is not absolute. Every pregnant woman has a different body shape, different diet, and different pregnancy times. So when can pregnant women reveal their pregnancy?

After pregnancy, when is it normal for a pregnant woman to show her pregnancy? Most of them show pregnancy in the past few months

Before pregnancy, a woman’s uterus weighs about 50 grams and is about 7 cm * 4.5 cm * 3.5 cm in size. It is only as big as a small duck pear. However, after pregnancy, As the pregnancy period increases, the fetus becomes larger and larger, and the uterus will expand accordingly. The details are as follows:

After 1 month of pregnancy, the fetus is about 0.2 cm long and weighs about 1 gram. After fertilization, the cleavage becomes a morula. , continue to divide to form a blastocyst and implant, and the fetal central nervous system and heart begin to develop. At 2 months of pregnancy, the fetus is about 3 centimeters long and weighs about 4 grams. The early heart has been formed and the heart is pulsing, and the five senses and limbs have begun to form. At 3 months of pregnancy, the fetus is about 9 centimeters long and weighs about 60 grams. The fetus' hands, toes and fingers are fully developed, nails and teeth have begun to develop, and the external genitalia have also begun to develop. At this time, the uterus is 2-3 fingers above the pubic bone. As can be seen from the picture above It can be seen that the uterus is still very small, the pregnant woman's abdomen is flat, and she is not pregnant yet.

Four months pregnant, the fetus is about 18 centimeters long and weighs about 120 grams. It moves frequently, sucks its thumb, and likes to rock back and forth in the amniotic fluid. At this time, the uterus is between the belly button and the pubic bone, and is obviously enlarged. When the uterus is much larger, the pregnant woman's belly begins to show her pregnancy. At the same time, the position of the uterus moves upward, and the pressure on the bladder disappears, and the pregnant woman's frequent urination will also slow down. However, due to the expansion of the uterus, the muscles on both sides are stretched, and the pregnant woman will have two sides of the lower abdomen. Soreness on one side or one side.

At the 5th month of pregnancy, the fetus is about 25 cm long and weighs about 340 grams. The motor and sensory nerves begin to develop, and the body is covered with lanugo hair and a little hair. At this time, the uterus has risen to the navel, which is already very large. As can be seen from the picture, the pregnant woman's belly is obviously bulging, and her pregnancy is very obvious and cannot be hidden at all.

From the perspective of fetal development, under normal circumstances, pregnant women start to show pregnancy at 4 months of pregnancy, and pregnancy becomes obvious at 5 months of pregnancy. However, the actual development of each fetus is different, and the diet of pregnant women is different. The amount of amniotic fluid and body shape are also different, which leads to differences in the time when pregnant women show pregnancy!

Pregnant women usually show pregnancy in the fourth month of pregnancy. Whether it is too early or too late is mostly related to these factors

1. The actual development of the fetus is different

Everyone knows that the calculation of gestational age during pregnancy is based on the first day of the last menstrual period. However, each pregnant woman’s ovulation period is different, and the implantation time of the fertilized egg is also different. This causes the actual gestational age of the fetus to be different from the calculated gestational age. There is a certain deviation. This deviation is generally within 2 weeks. For a fetus that implants early, the pregnant woman will show pregnancy slightly earlier; for a fetus that implants late, the pregnant woman will show pregnancy slightly later.

2. Is the gestational age calculation wrong?

Some pregnant women do not know how to calculate their gestational age, or they misremember the time of their last menstrual period, resulting in incorrect calculation of gestational age. For example, I was 3 months pregnant but mistakenly thought I was 4 months pregnant. For this kind of pregnant woman, during the early pregnancy check-up, you can confirm your gestational age with your doctor, and pay attention to judging the gestational age based on the embryo data, which is more accurate.

3. Dietary intake of pregnant women

Some pregnant women show pregnancy very early, and their belly is already very big in less than 3 months. Most of these pregnant women show pregnancy because of abdominal fat. It is caused by too much, which means that it is not the fetus that shows pregnancy but the fat! They eat improperly in early pregnancy, overeating or eating too many high-calorie, high-sugar, greasy foods, which leads to a large accumulation of fat, which is why they become pregnant.

4. Pregnant woman’s personal physique

In fact, the pregnant woman’s physique will also affect the time when she becomes pregnant. For example, if the pelvis of a pregnant woman is relatively narrow, her belly will bulge forward soon after pregnancy. If the pregnant woman's pelvis is wider, she will show pregnancy earlier; on the contrary, if the pregnant woman's pelvis is wider, she will show pregnancy slightly later.

5. Several other factors

In addition to the above four factors, the sooner or later pregnancy becomes apparent is also related to parity, number of fetuses, and amniotic fluid volume.

Generally speaking, the first pregnancy will show up slightly later, the second and third babies will show up slightly earlier; the belly of twins or multiple babies will be larger and the pregnancy will show up earlier; and although the amount of amniotic fluid has a range, there is also a higher amount. In the case of less amniotic fluid, pregnant women with more amniotic fluid generally have larger belly and show pregnancy earlier.

To sum up, most pregnant women begin to show their pregnancy when they are 4 months pregnant, their belly slowly bulges, and their body shape begins to change. However, the specific time varies from person to person and depends on the relationship between the pregnant woman and the patient. The actual development of the fetus! No matter when you reveal your pregnancy, pregnant women only need to eat healthily, protect themselves, and have regular prenatal check-ups!
