Normally, you will have your normal menstruation in about 30 days from the day of abortion. However, since abortion can damage the endometrium of the uterus, it may cause a delay in menstruation, which is normal for 7-10 days. If you have not had your period for more than 10 days, it is suggested that there is a persistent thinning of the endometrium caused by the abortion, or there may be cervical adhesions or cervical adhesions. After the examination, medication can be prescribed to induce menstruation according to the thickness of the endometrium. Also, abortion can cause prolonged menstrual irregularities, so it is important to observe future menstruation as much as possible. If there is prolonged menstrual irregularity, take short-acting oral contraceptives to repair the endometrium and regulate the menstrual cycle.
