When does a girl start having periods?:
A girls periods can begin from 8 to 16 years of age. Generally, they start when a girl is about 12. Researchers identified two genes that are involved in determining when girls begin menstruation. Menstruation is a major stage in a girls puberty. It is one of several physical signs that a girl is becoming a woman. Approximately 6 months before getting her first period a girl may detect more clear vaginal discharge. Unless the discharge has a strong odor, or causes itchiness, this is normal and nothing to worry about. The periods will occur regularly until the woman reaches her menopause. The menopause arrives generally when the woman is aged about 45 to 55.
