Why does a pregnant woman's belly fall down?

Pregnancy is divided into three stages: early pregnancy, mid-pregnancy, and late pregnancy. The changes in pregnant mothers are different in each stage, and the most obvious change is the size of the belly. In the late pregnancy, the pregnant woman's belly will become bigger and bigger, and the fetus will gradually mature. Some pregnant women find that their stomachs are dropping and they become very nervous and worried whether the baby is about to be born. So, what is the reason why pregnant women’s belly drops down?

Why does a pregnant woman’s belly drop downward? If a pregnant woman's belly drops down, it is likely that she has entered the pelvis. Engagement refers to the process in late pregnancy when the fetus, surrounded by amniotic fluid and fetal membranes, lies with its head down, buttocks up, and the whole body curled up, so that its head enters the pelvic cavity through the mother's pelvic entrance, thereby consolidating its body position. When the fetus enters the pelvis, many pregnant women often feel a tightness and pain in the abdomen.

As pregnancy comes to an end, the fetus in the womb is silently preparing for birth. He (she) will wait for the opportunity with his (her) head down, buttocks up and whole body curled up, surrounded by amniotic fluid and fetal membrane. Before delivery, the first thing the fetus is forced to do is to put its head through the mother's pelvic inlet into the pelvic cavity so that its body position is consolidated. This is what is medically known as "pelvic entry". It can be said that pelvic floor is the prelude to childbirth.

So, how long does it take for the fetus to enter the pelvis before delivery? Generally, a primipara can give birth 2 to 3 weeks after the pelvis is engaged, while a multipara who has given birth before often goes into labor immediately after the pelvis is engaged. Whether the fetus has entered the pelvis can only be determined through prenatal examination.

When the fetus enters the pelvis, many pregnant women often feel a tightening and heavy pain in their abdomen, and think that the fetus in their abdomen is descending, so they will rush to the hospital in a hurry. In fact, this situation is not a real sign of labor. The main differences are that first, the duration of uterine contractions is short, often less than half a minute; second, the contractions are irregular and relatively weak. Therefore, it is often called "false labor". But no matter what, the pelvis entering the pelvis means that delivery is approaching, and pregnant women can make all kinds of preparations based on this signal to welcome the arrival of the baby.

The above are the reasons why a pregnant woman’s belly drops. Through understanding, we can know that a dropping belly means that the fetus has entered the pelvis and the baby is ready to be born. At this time, pregnant women should not be too nervous. They should wait for the birth of the baby naturally and have a good rest to conserve their energy so that they can better welcome the arrival of the baby.
