The full course of pregnancy generally lasts 40 weeks and is clinically divided into 3 periods: early pregnancy, middle pregnancy, and late pregnancy. The 7th month of pregnancy is the late pregnancy stage. Pregnant women often feel paroxysmal abdominal pain in the middle and late stages of pregnancy, the reason for this is because of the increased burden on the abdomen and the whole body during the state of pregnancy, plus the number of abdominal pains will gradually increase as the weeks of pregnancy increase, which requires us to distinguish the causes of abdominal pain. Generally, abdominal pain can be divided into two conditions, physiological abdominal pain and pathological abdominal pain. Generally speaking, physiological abdominal pain is due to the enlarged uterus stimulating the lower edge of the rib cage, causing a dull pain in the rib cage. This abdominal pain usually lasts only a few seconds and is relieved without a feeling of falling. Pathological abdominal pain such as placental abruption often occurs in late pregnancy, which often indicates the possibility of preterm labor or rupture of the uterus, which is very dangerous, and if the abdominal pain persists in late pregnancy, you need to go to the hospital in time. To prevent complications such as DIC, postpartum hemorrhage, acute renal failure, amniotic fluid embolism, and more serious cases may lead to shock. If abdominal pain occurs in the 7th month of pregnancy, it is recommended to go to the hospital first, and if necessary, ultrasound examination, supplemented by fetal heart monitoring, should be done to exclude the possibility of preterm labor and placental abruption. In case of epigastric pain, it is also necessary to exclude rare spontaneous liver rupture, etc.
