The main symptom of a poorly repaired endometrium is irregular vaginal bleeding. If the endometrium is not repaired after abortion, the vaginal bleeding will be prolonged. In clinical practice, it is recommended to take short-acting oral contraceptive pills after abortion to repair the endometrium as soon as possible and to reduce the duration of vaginal bleeding and avoid the chance of infection. In addition, if the endometrial lining is not repaired well during menstruation, it is often caused by insufficient estrogen, which can lead to prolonged menstruation and dripping of menstrual blood during menstruation. Therefore, in the case of poor endometrial repair and irregular bleeding, if organic lesions are excluded after examination, estrogen or oral contraceptives can be used to give the appropriate treatment.
