The next day after the abortion stomach pain is a normal phenomenon, because whether it is a drug abortion, or artificial abortion, natural abortion, when the products of pregnancy from the uterine cavity discharged, will not stimulate the uterus to cause contractions and lead to lower abdominal pain, which is a normal phenomenon, but there will be corresponding vaginal bleeding, the amount of blood is not much, less than the amount of menstruation. If the stomach still hurts on the second day, it may be due to the following clinical reasons: First, there are residual tissues in the uterus, which will stimulate the uterus to contract, so it will lead to pain in the stomach. Second, the original inflammation, such as chronic pelvic inflammatory disease, after the abortion leads to a decline in body resistance, so there will be pain in the lower abdomen. Third, there may be other causes of abdominal pain. Therefore, if you still have abdominal pain on the second day after the abortion, you should actively go to the hospital for examination and treatment.
