There is no exact time for how long it takes for vaginal bleeding to clear up after an abortion, and it is generally considered normal for vaginal bleeding to clear up within 7-10 days. If the vaginal bleeding does not last longer than 10 days after the abortion and the amount of bleeding is not heavy, it is normal. If the amount of bleeding exceeds the amount of menstruation or the bleeding is still not clean for more than 10 days, you must go to the hospital as soon as possible for an ultrasound examination, which may be caused by incomplete abortion, or may be caused by infection in the uterine cavity or poor uterine regeneration, and must be treated as soon as possible. Therefore, after abortion, if the bleeding is more than 10 days, you can go to the hospital in time to check the situation of the uterine cavity, there are bruises, residues and timely removal, you can clear the uterus under hysteroscopy and ultrasound monitoring, which is conducive to a one-time removal of the uterus, and then antibiotics and pro-contraction medication are given after the operation.

Sexual intercourse is prohibited for one month after the abortion.
