At 23 weeks, you are in the middle of your pregnancy. At this time, the fetus grows and develops very rapidly, and the uterus enlarges faster, which can cause abdominal pain by pulling the uterine wall taut. In addition, the enlargement of the abdomen can cause the abdominal organs to be squeezed and the ligaments around the uterus to be stretched, which can cause slight pain in the abdomen. Especially when the enlarged uterus touches the lower edge of the ribs, it can make the abdominal pain worse, which is a normal physiological phenomenon. However, if the abdominal pain is severe and cannot be significantly relieved after rest and postural adjustment, it is important to consider whether there is any obstetric disease, such as pre-miscarriage, placenta previa, ovarian cysts, or whether there are other diseases. You should go to the hospital for diagnosis and treatment. In addition, pregnant women may also have abdominal pain caused by digestive and gastrointestinal diseases, which should also be diagnosed and treated in the hospital.
