What are the symptoms of baby's pelvic floor?

In the later stages of pregnancy, the baby will prepare for the birth on its own, with its head down and buttocks up. Generally, delivery may occur about two to three weeks after the baby enters the pelvis. There will be a feeling of sinking in the lower abdomen when the baby enters the pelvis, but it usually won't last too long.

symptom

When the fetus enters the pelvis, many pregnant women can feel the fetus's position descending, which may be accompanied by a slight feeling of pain. The entire process may be completed in less than half a minute. To determine whether the fetus has entered the pelvis, an obstetric examination is needed.

Feel

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.

judge

The fetal head pointing downwards does not necessarily mean that the fetus has entered the pelvis, but if it is not in the head position, but in the transverse position or breech position, it is impossible for the fetus to enter the pelvis.

If the fetus is not engaged in the pelvis, the doctor will open the index fingers and thumbs of both hands and press the fetal head on the upper edge of the pubic symphysis. If the fetal head is engaged in the pelvis, it cannot be shaken and is fixed. If the fetal head is not engaged in the pelvis, it can move, and there is a distance of two horizontal fingers between the fetal head and the pubic bone.

Generally speaking, there are several reasons why the fetus cannot enter the pelvis, including cephalopelvic disproportion, asymmetry between the fetal head and pelvis, the fetus is too large, the umbilical cord is wrapped around the neck, the fetal head cannot descend, and placenta previa.

The disadvantage of not being able to enter the pelvis is that it can easily lead to premature rupture of membranes, resulting in caesarean section, etc.
