In late pregnancy, as the fetus grows, the mother-to-be’s abdomen and body burden gradually increase, and the number of abdominal pains nearing delivery increases significantly compared with the original middle term. Physiological abdominal pain, as the baby grows up, the mother-to-be’s uterus also gradually increases in size, and the enlarged uterus constantly stimulates the lower edge of the ribs, causing dull pain in the ribs of the mother-to-be, which is physiological and does not require special treatment, and the pain can be relieved by lying on the left side. In late pregnancy, when the mother-to-be rests at night, she may experience lower abdominal pain due to false contractions, which usually lasts only a few seconds, but indirectly lasts for several hours, without the feeling of falling, and the symptoms can be relieved during the day. Pathological abdominal pain, placenta abruptio mostly occurs in late pregnancy. The mother-to-be may have gestational hypertension syndrome, chronic hypertensive disease, abdominal trauma, and tearing pain in the lower abdomen is a typical symptom, mostly with vaginal bleeding. The degree of abdominal pain is affected by the size of the premature abruption, the amount of blood, the internal pressure of the uterus and whether the myometrium is broken, etc. In severe cases, the abdominal pain is unbearable, the abdomen becomes hard, the fetal movement disappears, and even shock. If the mother-to-be has high blood pressure during late pregnancy or suffers from abdominal trauma, she should go to the hospital in time to prevent accidents. If the mother-to-be suddenly feels continuous pain in the lower abdomen, it may be premature labor or a precursor rupture of the uterus, and she should go to the hospital in time without delay.
