When does I start my period

Okay, so there's no exact date, but most kids get their first period between 10 and 13 years old. It can totally happen earlier or later though, so don't stress if you're not in that exact window.

Your first period is usually one of the last things that happens as your body goes through puberty. Like, you'll probably notice other stuff first, right? Things like your breasts starting to develop (even if it's just a little bit), pubic hair growing, and a growth spurt where you get taller really fast. Also, a few months before your period, you might start seeing a clear or whitish discharge on your underwear. That means your body is getting ready for real!

There's a quiz on this site that helps you figure out roughly how close you might be, because it asks about all those signs and gives you a better idea. It's pretty cool. Try it out: how close is my first period?
