Women who have a small amount of intrauterine residue after abortion are treated conservatively with mifepristone. After taking mifepristone, women may experience uterine contractions with or without abdominal pain and bloody vaginal discharge containing blood clots or flesh-like tissue, which will disappear gradually after 3-7 days. If the vaginal discharge is less and not clean after taking mifepristone, or if the vaginal bleeding is more and bright red, or if the abdominal pain is obvious, it is considered that the effect of medication is not good and the intrauterine residue is not discharged smoothly, so it is necessary to have a timely examination and perform the operation to clear the uterus as soon as possible to avoid prolonged bleeding which may lead to anemia and even affect the recovery of the uterus, which is not conducive to normal fertility in the future. Therefore, it is important to follow the doctor’s instructions for follow-up after abortion.
