How do you know youll have your period soon?

Answer 1

Well, you'll probably have some cramps that are lower down and across your back. So you might snap at people without meaning to, or just be in a bad mood. Also MOST NOT ALL girls have their periods when they're twelve or thirteen or maybe even eleven. Not a lot of girls have it when they're eight or nine or ten or sixteen or fifteen. Most start menstruating (having their period) when they're 11-13. So if you're eleven or a couple years older you should carry around some sanitary napkins (pads) in your backpack or your purse just in case. But if you're mom had it late, at like 14, then you'll probably be kind of late too. Or if she was early then same thing. Um...that's pretty much it.
