If the bleeding has stopped for 3 days after the abortion procedure and you experience vaginal bleeding again, it is considered abnormal. Generally, the amount of vaginal bleeding after an abortion will gradually decrease with time and stop within a week. However, if the bleeding stops again after 3 days, it is definitely an abnormal situation. At this time, you need to go to the hospital for an ultrasound examination to clarify the cause of the bleeding, to see if the bleeding is caused by poor uterine regeneration, or the bleeding is caused by the residue in the uterine cavity, incomplete abortion, incomplete suction, or the bleeding is caused by infection in the uterine cavity, and then you can carry out the symptomatic treatment according to the cause after clarification of the specific cause.
