How many days does the menstrual period last to be considered normal?

Patient's question:

No

Doctor's answer:

The duration of menstruation is generally 3-7 days, with bleeding volume within 100 milliliters, peaking on the 2-3rd day. Menstrual blood is usually dark red and does not clot, apart from blood, it also contains fragments of the endometrium, cervical mucus, and vaginal epithelial cells. If there is an odor or blood clots, it may indicate the possibility of gynecological inflammation. It is best to wait until menstruation ends for 3 days before going to the gynecology department of the hospital for relevant examinations to confirm the diagnosis and receive symptomatic treatment.
