If the menstrual period has not yet come after taking Chinese menstrual regulating drugs, it is advisable to find out if you are pregnant by urine HCG. If you are not pregnant, it is recommended that you can take progesterone orally to promote menstruation. Progesterone is a progestogen taken orally, which can cause abnormal thickening of the endometrium. When the endometrium loses the support of exogenous progesterone after stopping taking it, withdrawal bleeding will occur. It is recommended that if you take progesterone orally for three days, you will have your period after 3-7 days of discontinuation. If you still do not have your period on the eighth day of discontinuation, you must have an ovarian function test to rule out the possibility of premature ovarian failure. In addition, if there is no menstruation, amenorrhea caused by polycystic ovary syndrome should also be ruled out clinically. It is recommended that an ultrasound examination be done to see if the uterine attachments are normal.
