When Do Girls Get Their Period?

If you’re wondering, “When do girls get their period?” The truth is, it depends. Many first periods (called menarche) happen between ages 9 and 15, with most girls experiencing it at age 12. Some start earlier, others later, and both are healthy and normal! Every body moves at its own pace, guided by a mix of genetics, health, and environment.

Navigating the First Period: When Do Girls Typically Start Menstruating?

The first period can feel like a big unknown. Often, your child’s body will give little hints that a period is on the horizon. Breast development, new hair under the arms or around the pubic area, or whitish vaginal discharge are all natural signs that menstruation could begin within the next year or two.

The most important part is approaching this milestone with openness, patience, and reassurance. Let your child know it’s always okay to ask you questions, share worries, or just talk about what’s on their mind. Even if you don’t have an answer right away, simply listening and responding with kindness helps build trust. By keeping the dialogue supportive and judgment-free, you remind them that periods aren’t something to hide; they’re a natural part of growing up. Plus, with the right tools, like leakproof period underwear or reusable menstrual cups and menstrual discs, your child can feel prepared and confident from day one.
