First Period Facts

A girl's first period is referred to as menarche. This marks the beginning of menstruation, a physical process that lasts until menopause.

Timing

• Most girls get their first period between the ages of 12 and 13, but it can occur from ages 9 to 16.

Symptoms

• Menarche generally occurs around two years after the development of breasts. Some girls may notice a sticky white discharge for a few months prior to getting their first period. Other side effects like cramping or bloating may occur during menstruation.

Factors

• Cultural and genetic factors can both affect the age of menarche. Being underweight or undernourished can delay the onset of menarche.

Significance

• Many cultures celebrate menarche as a symbolic step towards becoming a woman. Others perceive menstruation as a simple physical occurrence.

Effects

• Irregular periods are normal; many girls take up to two years to have a regular menstrual cycle. Generally, bleeding lasts for three to seven days, and the entire cycle lasts from 21 to 40 days.
