Late pregnancy mainly refers to 28-40 weeks of pregnancy. If a pregnant woman has stomach pain and a feeling of defecation, it can be caused by the fetal head entering the pelvis causing the uterus to press on the rectum and produce bowel movements, and at the same time induce pseudo contractions, which can lead to symptoms of stomach pain. If the symptoms of abdominal pain last for a short period of time, it is necessary to relax and avoid excessive tension to relieve the uterine contractions at this time. It is also necessary to closely observe the interval of contractions, fetal heartbeat and abnormal changes of the pregnant woman and prepare for delivery. In addition, if the uterine contractions are too strong, resulting in stomach pain and the urge to poop, it may be a sign of labor. Of course, abnormal conditions such as placental abruption cannot be ruled out, and timely medical consultation and corresponding treatment are needed to protect the safety of the pregnant woman and the fetus. Pregnant women should pay more attention to good living habits during late pregnancy, ensure sufficient sleep, eat a light diet, do not eat cold, greasy, spicy and stimulating food, and go to the hospital in a timely manner if they have symptoms of discomfort.
