Is it because the fetus is malnourished when the pregnancy is not obvious? What is the reason for the pregnancy not being obvious?

We all know that after a woman becomes pregnant, her body will undergo many changes, and showing pregnancy is one of the most common phenomena. Due to the different physical constitutions and developmental conditions of pregnant mothers, the time and size of pregnancy are also different. Some pregnant mothers show their pregnancy, while others do not. So does not showing pregnancy mean that the baby is malnourished? Let's take a closer look below!

Is it because the baby is malnourished if the pregnancy is not obvious?

Whether a pregnant woman's pregnancy is visible has nothing to do with whether the fetus is malnourished.

The size and shape of the mother’s belly cannot be used to judge the baby’s developmental status, because the size of the mother’s belly is not only related to the size of the fetus, but also closely related to many factors!

During pregnancy, the mother's belly changes the most. In fact, it should be the uterus. The uterus is the organ that changes the most during pregnancy. As the pregnancy progresses, the fetus, placenta and amniotic fluid are formed and developed, and the mother's uterus will gradually increase and soften. In the early stages of pregnancy, the fetus is still very small, and the amount of amniotic fluid is not much. The mother's uterus is still in the pelvic cavity and is about the size of a fist. Therefore, mothers are generally not pregnant in the early stages of pregnancy. However, the uterine wall where the fertilized egg implants will protrude significantly, so some mothers will find that their lower abdomen has a slight bulge. At 12 weeks of pregnancy, the mother's uterus is about the size of a grapefruit. The enlarged uterus gradually extends beyond the pelvic cavity and can be touched above the pubic symphysis. At this time, with the development of the fetus and the increase in the amount of amniotic fluid, the mother's belly will begin to show. Generally speaking, most mothers begin to show their pregnancy at 4 months of pregnancy, which is 16 weeks, which is the saying "hide three but not four".

Factors that affect pregnancy

The reason why the size of the mother's belly cannot be used to judge the development of the fetus is that the size of the belly is not only related to the size of the fetus, but also to the following reasons:

Incorrect calculation of gestational age

Our gestational age is usually calculated based on the last menstrual period. If the mother cannot remember the last menstrual period, or remembers the wrong date of the last menstrual period, then the gestational age will be calculated incorrectly, and the actual gestational age may be too long or too short. For example, if the last menstrual period is remembered incorrectly, the pregnancy is calculated to be 4 months, but it is actually only 3 months. If the mother's menstrual cycle is relatively long and the ovulation period is late, it is also easy to calculate the month too long, which will result in the situation where the pregnancy is not obvious in the month when it should be.

Mother's weight gain

In the early stages of pregnancy, some mothers have large reactions and cannot eat, so sometimes they do not gain weight but instead lose a few pounds. In this case, mothers' pregnancy will show later. After the second trimester, the reaction disappears, the appetite increases, the weight will increase rapidly, and the belly will gradually grow bigger. Some mothers do not have a big reaction in the early stages of pregnancy. Sometimes they have a good appetite and eat more, and gain weight significantly. The big belly is actually fat. Gaining too much weight during pregnancy does not mean that the baby is bigger, it just makes the mother's body bigger than others. In the month when the pregnancy should be shown, because of the extra fat, the belly will look bigger than that of mothers in the same gestational week.

The mother’s body shape, size, and frame size

For petite mothers, the belly will be smaller, lower, and located in the front. If the mother is thin, the pregnancy will not be easy to show. Sometimes the belly of a 6-month pregnant woman looks like the belly of others at 4 months. If the mother's skeleton is relatively large, the fetus has enough space to grow, and the mother's belly will not be easy to show. If the mother has more belly fat before pregnancy, then the belly may show earlier after pregnancy, and it will look bigger than the belly of mothers in the same gestational week. Mo's belly had more belly fat before pregnancy, and it showed earlier after pregnancy. At 6 months of pregnancy, her belly looked like someone else's belly about to give birth, so much so that when others saw me, they asked if I was going to give birth.

Multiple pregnancies

Multiple pregnancies here refer to mothers who are pregnant with their second or third child. Generally, the belly of mothers who are pregnant with their second or third child will show earlier and will be bigger. This is because the belly is like a balloon. After "inflating" once, the abdominal muscles have become looser, making it easier to show the belly again. Compared with mothers with loose abdominal muscles, the belly of mothers with firmer abdominal muscles is not so obvious.

Amniotic fluid volume

We mentioned earlier that the amount of amniotic fluid will also affect the appearance of the mother's belly. During pregnancy, the amount of amniotic fluid gradually increases with the progress of the gestational weeks. At 8 weeks of pregnancy, the amount of amniotic fluid is about 5-10ml, at 20 weeks the amount is about 500ml, and at 36-37 weeks the amount of amniotic fluid is the highest, around 1000-1500ml. If there is more amniotic fluid, the mother's belly will appear bigger, and if there is less amniotic fluid, the belly will appear smaller.

In addition to the above points, the fetal position and the location of the placenta may affect the size of the mother's belly.

How long does it take for pregnancy to show?

Generally speaking, during the 16th week of pregnancy, the mother's pregnancy will begin to show.

If the pregnancy is obvious before 16 days of pregnancy, it is not because the fetus has grown or the uterus has enlarged. It is because the pregnant mother is fat or has thick abdominal fat.

Because at the 16th week of pregnancy, the uterus has enlarged beyond the pelvis. If the pregnant mother measures the uterine height by hand at this time, the position between the umbilicus and the pubic region is the uterine fundus.

However, before the fourth month of pregnancy, the uterus is still relatively small and hidden in the pelvic cavity. Therefore, the pregnancy is not obvious before the fourth month of pregnancy, but it starts to show after the fourth month of pregnancy.
