When a woman experiences amenorrhea, if pregnancy has been ruled out, she will usually take progesterone orally for 5 days and have her period within 1 week of stopping the medication. If after taking progesterone, there is no menstruation for about 1 week after stopping the medication, it indicates that the estrogen level in a woman’s body is insufficient. At this time, oral progesterone will not bring about menstruation either. In this case, women should not be anxious and can supplement their body with estrogen, such as taking regular oral estradiol valerate, also known as Tegretol, for 21 consecutive days. On the last 11 days, that is, from the 15th day of taking the pill, add progestin-based drugs, such as dydrogesterone tablets and progesterone capsules, to do the cycle. Usually 3 cycles is 1 course of treatment, which can help women restore their normal menstrual cycle and in some cases, normal ovulation.
