If you have had a medication abortion for 11 days and there is still vaginal bleeding, you should first rule out whether the medication abortion was incomplete. If there is no residual pregnancy product in the uterine cavity after ultrasound examination, vaginal bleeding is normal. This is because the vaginal bleeding is longer than that of abortion, usually around 15-20 days. This is because after a medical abortion, the trophoblast cells are not completely apoptotic, causing repeated vaginal bleeding, which is one of the main features of medical abortion and is a common clinical side effect. Therefore, after a medication abortion, it is generally recommended to take oral mifepristone for 3-5 days, which can promote the apoptosis of trophoblast cells. It reduces the duration of vaginal bleeding.
