Two months without menstruation, first of all to exclude the existence of endocrine hormone disease, because when there is polycystic ovary syndrome, when there is prolactinemia, it will cause menstruation for a long time, can also cause amenorrhea. So at this time it is due to endocrine hormone imbalance that menstruation does not come for two months. For example, if pregnancy can cause a long delay, this time must be ruled out there is no chance of pregnancy, pregnancy can also cause two months or even longer without menstruation. For example, when there is ovarian hypoplasia, especially in the endocrine hormone test, suggesting that the ovulation hormone is out of the normal range of values, this time will cause menstruation for a long time without menstruation, and there is also a decrease in menstruation. For example, if there are cysts in the adnexa bilaterally, the normal ovarian function is affected, and menstruation may be absent for a long period of time.
