Menstruation in women is regulated by thalamus-pituitary-ovarian gonad axis. Mental factors, emotional fluctuations, environmental changes, pregnancy, age, diseases, drugs, nutritional status, etc. will all cause abnormal function of this gonadal axis, leading to abnormal menstruation.

Guidance: So I suggest you go to the gynecology department of a regular hospital. First, explain your medical history to the doctor. The doctor will comprehensively analyze your situation and clinical symptoms, and carry out related tests, such as blood test, B-ultrasound, hormones, etc.
