If you feel that you are going to have your period but not coming, you should go to the hospital for an early pregnancy check, which may be caused by pregnancy. If your period is not delayed for more than a week, it is considered normal and no special treatment is needed. If your period is not coming for more than a week, you can check the endometrium through ultrasound. If the endometrium is thicker, you can also take progesterone under the guidance of a doctor to promote menstruation, usually pay attention to sufficient sleep, not to stay up late, and recommend relaxation, which can prevent endocrine disorders and delayed menstruation.
