Generally about a week after the abortion, there will be no vaginal bleeding, if the bleeding still occurs 20 days after the abortion, you need to go to the hospital for a review, usually a review of HCG and gynecological ultrasound. If this happens, the possibility of incomplete abortion cannot be ruled out. If it is determined that the abortion is incomplete, it is recommended that the uterus be cleared, which can achieve the purpose of stopping bleeding and also remove the lesions. After the removal of the uterus, it is recommended that prophylactic oral antibiotics be taken for treatment, and it is recommended that the endometrium be regulated with contraceptive pills such as Yosmin and Yosiyue, and that follow-up examinations be conducted routinely for one week after the operation.
