If the patient did not have menstruation for 2 months, in this case, if there is no sexual intercourse, we can consider giving progesterone withdrawal treatment, such as the application of dydrogesterone, imaxicin, angiotensin, progesterone injection, and observe for 14 days after stopping the medication, and the menstruation will usually come within two weeks. If menstruation has not come for 2 months, and the patient has sexual intercourse and does not use contraception, in this case, the first thing to do is to draw blood to check the HCG value, to exclude the delay of menstruation caused by pregnancy. If the blood HCG value rises, it suggests that pregnancy is the cause. If the HCG value does not rise, in this case, we need to further check the sex hormone six test. If the sex hormone test is within the normal range, progesterone withdrawal can be considered. If the hormone profile is suggestive of postmenopausal levels, hormone replacement therapy may be indicated if necessary, depending on the patient’s needs.
