Pregnancy may cause pain in the lower abdomen, lower back and pubic symphysis. 1. Lower abdomen: some women will experience uterine contraction pain without bleeding after pregnancy, most of the pain is mild and can be tolerated. 2. Lower back: After pregnancy, ligaments and joints become loose due to the secretion of relaxin by the placenta. When the center of gravity of the pregnant woman changes after the uterus enlarges, the lumbar paraspinal muscles continue to show contraction, which can cause women’s low back pain, and the symptoms will be relieved after bed rest. 3. Pubic symphysis: After pregnancy, the pubic symphysis is separated, resulting in pain at the pubic symphysis. If pregnant women do not pay attention to supplement vitamin D and calcium, causing osteoporosis, can cause the pubic symphysis pain obvious. Women take bed rest and calcium supplements, and the pain improves after delivery. Pregnancy can cause pain in some parts of the body. When abnormal symptoms occur, consult a doctor in time, identify the cause under the guidance of the doctor and give appropriate treatment.
