Most girls get their periods somewhere between the ages of 9 and 16. But it's not unheard of for a girl's period to start before age 9. Rather than age, you can look for signals in your body. Most girls don't get their period until they weigh at least 100 pounds and have started developing breasts.
Next comes the pubertal growth spurt. Lastly, menstruation begins (called menarche), on average, 2-2.5 years after the onset of puberty. The mean age for a girlâs first period is 12.75 years.Wide variations are seen in the sequence and timing of these events, but peak growth velocity (fastest growth rate) always precedes menarche.ow for the crucial information: The earlier before age 12 a girl starts her period, the higher her lifetime risk for breast cancer (probably from the prolonged estrogen exposure). The highest average risk for breast cancer is in non-Hispanic white women, where it is 1 in 8, or 12.5%.
