In case of delayed menstruation for the second time after an abortion, first of all, a checkup is needed to rule out another unwanted pregnancy. If pregnancy is ruled out, it is recommended to have a pelvic ultrasound to see if there are any uterine adhesions, and it is better to have a direct hysteroscopy. Hysteroscopy can provide a clearer picture of the uterine cavity, and for patients who are identified with uterine adhesions, the adhesions can be separated surgically under hysteroscopy. In addition, if there is a delay in menstruation after the surgery, it is considered that there may be a relationship with damage to the endometrium. Therefore, at this time, it may be necessary to take appropriate medication for repairing the endometrium, such as Tocopherol, vitamin E and so on. At the same time, you should also strengthen your nutrition and strengthen your body. Also be sure to do a good job of contraception to avoid unwanted pregnancies.
