Physical changes of puberty in girls

Normally, menstrual bleeding in each period is on average 35 to 60 ml (less than one cup) of blood and tissue. Menstrual flow usually leaves the body slowly and gradually in 3 to 7 days.

Most bleeding occurs between the first and third days of menstruation and decreases in the following days or may appear as light blood flows. It is worth noting that during menstruation, hormonal changes in many girls lead to discharges other than menstrual blood. These discharges are usually pale yellow or white or colorless and have no -or little odor.

If these discharges turn brown or green or have a strong odor or cause itching and burning, see a health care provider.
