Previously, your menstrual cycle was normal, but now it only comes once every three or four months. What are you eating?

Patient's question:

Okay, here is the translation following your instructions:
After two years of menstruation, it only comes three or four times.

Doctor's answer:

Hello, it may be caused by endocrine disorders leading to menstrual disorders. Appropriate medication can be used. It is recommended that you take some progesterone, and hormone 6 tests can be conducted if necessary.
