What is a normal age for a first period?
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 well.
See a doctor promptly if
- Bleeding between periods, after sex, or any bleeding at all after the menopause
- Soaking through protection hourly, passing very large clots, or feeling faint, breathless or dizzy with bleeding
- Sudden severe one-sided pelvic pain, especially with a late or missed period. This needs emergency assessment
- Pelvic pain with fever, foul-smelling discharge or feeling generally unwell
- No periods for three months or more when you are not pregnant, breastfeeding, or on a method that stops bleeding
- New heavy or irregular bleeding starting after the age of 45, or any change in a long-established pattern
