Why Haven't I Started My Period Yet?

In this Ask AMAZE video, we answer common questions about first periods and puberty, including: What age most people start their period? Why some people start later than others? How hormones affect your menstrual cycle? Can intense sports delay your period? When should you see a doctor? Most people get their first period between ages 8–13, but starting later is normal too. Body type, hormone levels, and physical activity all play a role. If you’re concerned about delayed menstruation or other symptoms, talking to a healthcare provider can help you feel reassured. Puberty looks different for everyone — and that’s okay. [AA-066]
