What is the reason for my girlfriend's irregular menstruation?

Patient's question:

No

Doctor's answer:

Considering it might be menstrual irregularity, generally mood, environment, and physical condition can all affect menstruation. You can check your endocrine system, and also have a color Doppler ultrasound to examine the uterine cavity. Actively treat the cause, and you can try taking Wuji Baifeng Wan and Xiaoyao Wan. Appropriately supplement estrogen and eat more beans.
