If the menstrual flow becomes low after a medical miscarriage, it may be caused by endocrine disorder due to medical miscarriage, so you need to go to the hospital for a hormone test. If it is caused by low estrogen in the body, you need to take oral supplementation under the guidance of the doctor to regulate the symptoms and observe the growth of the endometrium. In addition, low menstrual flow after medical abortion may also be caused by thinning of the endometrium or adhesions in the uterine cavity, etc. It is best to have a 3D ultrasound examination and, if necessary, a hysteroscopy to clarify the cause. If the endometrium is damaged or the uterine cavity is adherent and the adhesions are thick under hysteroscopy, it is generally recommended to take oral supplementation to stimulate the endometrial growth. If it is caused by endometritis, oral levofloxacin and tinidazole can be administered, but standardized treatment is required. After a medical abortion, it is important to take rest and eat a light diet. Intercourse is prohibited for one month after a medical abortion, otherwise it may affect the recovery of the endometrium. In addition, if you have intercourse after a medical abortion, you must take good contraceptive measures to avoid another pregnancy.
