After undergoing an abortion procedure, patients may experience mild pain in the initial days and vaginal bleeding resembling menstruation for 3–7 days. It is important to monitor for worsening abdominal pain or abnormal bleeding.

Bleeding after a vacuum aspiration is a result of the uterus not contracting properly, or blood vessels failing to constrict to stop the bleeding. If the bleeding is heavy and prolonged, it is extremely dangerous, and you should seek a gynecologist immediately to avoid potential complications.
