Hello doctor. My menstrual cycle is usually on the 4th. But on the 3rd, I see some discharge and the color is not red like other menstrual days.

The menstrual cycle is a monthly occurrence in the female reproductive system. In medical terms, menstruation is the process by which a woman discharges (through the vagina) blood and other substances from the lining of the uterus at a certain time each month and occurs from puberty until menopause (the cessation of regular menstrual cycles), except during pregnancy. This process lasts about 3-5 days.
