How to determine if it's bleeding or menstruation after people have passed by

Patient's question:

No

Doctor's answer:

Hello, according to what you said, it is considered menstruation. Menstrual blood generally accompanies shed endometrium. If you are not sure, you can go to the hospital for a systematic examination. The breast pain and other reactions during menstruation are caused by fluctuations in hormone levels, and they vary from person to person. Even if there are none, it is normal.
