Menstruation

Most menstrual periods last from 3 to 5 days.

Menarche

Menarche refers to the first menstruation of a girl. It usually happens at the age of 12, but can begins at any time between the age of 11~14. Menarche does not occur till the age of 16, which should be paid attention. The emergence of menstruation is a sign of maturity and also considered to be a sign of fertility.

When you menstruate, there will be a flow of blood from the vagina. It may be brown initially, but will turn to red before it stops completely. Periods may last 4-5 days long, in some cases; it may even take 7 days.
