How do I know when my first period might be coming?

Okay so there are definitely some signs that your first period is getting closer, and it's not like a total surprise. Your body starts giving you little hints.

First up, your breasts will start to develop. Not like overnight, but you'll notice little buds forming. Then you'll usually have a growth spurt, so you might get taller and your feet might grow a bit. Super weird but true. Also, you might start seeing some white or yellowish discharge in your underwear, which is totally normal and means your body is getting ready for your period. It's like your body is doing a little spring cleaning.

Most people get their first period between ages 10 and 13, but some get it earlier or a little later, and that's all good. Everyone's body is different. If you want a fun way to guess when yours might show up, there's a quiz on this site that helps you figure it out: how close is my first period?
