The pain in the lower abdomen at 32 weeks of pregnancy is mostly caused by irregular contractions of the uterus, because during this period the fetus moves with a large amplitude of the limbs moving sideways, which easily touches the inner wall of the uterus, resulting in a slight pain, which can be relieved and improved after rest. During this period, you should pay attention to check the change of fetal heartbeat, if there is no problem with fetal heartbeat, you do not need to be too nervous and do not need to deal with it. If there are gynecological diseases, pelvic inflammatory disease or tubal inflammatory disease, appendicitis and other diseases, the pain on the right side of the lower abdomen may also occur, which is manifested as prolonged and continuous pain, and cannot be relieved after rest.
