The pain in the abdomen after medical abortion is due to the contraction of the uterus, which promotes the discharge of blood from the uterine cavity and the recovery of the uterus. However, if the pain is severe, or if the pain is accompanied by more than vaginal bleeding, the abortion may not be clean. If the pain is severe, you should go to the hospital in time for a review and perform an ultrasound examination to understand the condition of the uterine cavity and whether there is residual uterine cavity. If the abdominal pain is within seven days after a medical abortion, it is normal and can be temporarily observed without treatment, as abdominal pain or vaginal bleeding can occur after a medical abortion as well as after an abortion.
