Okay, here is the translation following your instructions: Menstruation starts with a light flow for three days, and only becomes heavy on the fourth day. Is this normal?

Patient's question:

No

Doctor's answer:

This is a manifestation of menstrual cycle disorders. You don't need to worry too much about it now. If there are no other symptoms, it should be related to your diet, lifestyle, or emotions. Wishing you good health
