After the fetus is in the pelvis, you will not feel any stomach pain because the fetal head is in the pelvis very slowly and for a long time. In the late pregnancy, as the fetus is first revealed, the lower part of the uterus will gradually lengthen and become thinner, and the fetal head will gradually descend into the pelvic cavity. As the height of the fundus of the uterus becomes smaller after the fetal head enters the pelvis, the pressure on the upper abdomen becomes lighter, and pregnant women will feel less chest discomfort, have a feeling of emptiness in the stomach, increase their appetite and enhance their digestive function, but at the same time, because the fetal head descending will press on the bladder and rectum, pregnant women will have symptoms such as frequent urination and constipation. When the fetal head is very low, pregnant women will also have a feeling of falling abdomen, which will be aggravated after moving around, and a feeling of foreign body on top when they are sitting. Therefore, although there are many signs and symptoms after the fetal head is in the pelvis, there is usually no stomach pain.
