After a medication abortion, the first step is to assess whether the medication abortion was successful. The criterion for evaluating success is to see with the naked eye whether the fetal sac is completely expelled, and another criterion is to perform an ultrasound examination to assess whether there is any residue in the uterine cavity. Normally, if the medical abortion is successful, the fetal sac is completely expelled and there is no residue in the uterine cavity, the medical abortion is considered successful. Generally speaking, vaginal bleeding after abortion will not exceed two weeks and the amount of bleeding will not exceed the amount of menstruation. If the bleeding continues for an excessive period of time after a medical abortion or if the amount of bleeding exceeds the amount of the menstrual period, it is considered an abnormal manifestation. In this case, consider whether there is a problem of incomplete medical abortion or the presence of gestational trophoblastic disease. In either case, abnormal vaginal bleeding after a medical abortion requires prompt examination and evaluation at a hospital. If the abortion is incomplete, a prompt evacuation procedure is required to facilitate the expulsion of residual pregnancy tissue. If the abnormal vaginal bleeding is due to other infectious factors, or if the abnormal vaginal bleeding is due to gestational trophoblastic disease, appropriate targeted treatment is required.
