What is a normal age for a first period?

Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS

Anywhere from 10 to 15 is within normal, typically about two years after breast development begins. The first years of cycles are often irregular while the hormonal axis matures, which is expected rather than worrying.

Investigate when a period has not arrived by 15, or within three years of breast development starting, or if periods begin before age 8.

For parents: pads ready in the school bag, matter-of-fact conversation early, and iron-rich food once cycles begin covers the practical side beautifully.
