When does menstruation begin?
The age of period is similar to mother’s period age and it’s set with genetic characteristics. If there’s no health issue that will change the time or affect it, menstruation starts between 9 to 16 ages. Menstruation that starts before the age of 9 indicate precocious puberty. Also if menstruation hasn’t started after the age of 16, one should go to a specialist and try to determine the reasons.
