Belly pain after pregnancy is an abnormal phenomenon, and the vast majority of women do not experience belly pain after pregnancy. If there is stomach pain, it is usually due to preterm miscarriage, lack of progesterone in the body or sexual intercourse, or a history of trauma or heavy work after exertion, which may cause contraction of the smooth muscles of the uterus, which may result in stomach pain. In addition, if you have had chronic pelvic inflammatory disease in the past, you may also experience stomach pain after pregnancy, because after pregnancy, the inflammatory state of the pelvis will be aggravated by congestion, so local pain will occur. It is recommended to take into account the clinical history and also recommend a comprehensive analysis of progesterone and blood HCG, as well as the results of ultrasound examination, and give the appropriate treatment in clinical practice. In case of stomach pain, bed rest is recommended.
