Is a small menstrual flow caused by endocrine disorders?

Patient's question:

Menstrual volume is low, qi and blood deficiency, spots on the face, no problems found in gynecological health check-ups, please ask if the low menstrual volume is caused by endocrine issues

Doctor's answer:

Hello, based on the form you provided, it seems that your hormone check doesn't show any major issues. Don't worry too much.
I suggest you don't get overly anxious or stressed. Regarding the situation you mentioned, your hormone levels should not be a significant problem. Relax and monitor the growth of your follicles. It's best to have intercourse during ovulation.
As a patient, you should maintain a positive mindset and face the illness with optimism. Only in this way can you enhance your immunity and strengthen your belief in overcoming the disease. I believe this will definitely help drive the illness away.
