Normally, the vaginal bleeding after abortion is usually not more than a week, if the vaginal bleeding after abortion is more than a week and has reached half a month, it belongs to an abnormal situation, which may be related to the poor recovery of the uterus or incomplete abortion. If there is a delay in menstruation after the abortion, it is more important to consider these points. In this case, it is recommended to go to the hospital for ultrasonography and hormone six tests to clarify the specific causes of delayed menstruation, and then carry out symptomatic treatment. If it is caused by poor uterine regeneration, you need to add motherwort for symptomatic treatment; if it is caused by incomplete abortion, you need to do the purging treatment; if it is caused by uterine adhesion due to abortion, you need to do the hysteroscopic treatment.
