How do I know if I'm starting my period tomorrow?

Okay, so you're wondering if your period is literally going to start tomorrow. I get it, that feeling of 'is this it?!' can be wild!

No one can tell you for sure if your period will start exactly tomorrow, but there are some super common signs your body usually gives you that it's getting ready. Your body might feel a little different than usual, like maybe your stomach feels crampy or you're extra tired. Some people get a headache or their boobs get a little sore. You might also notice some discharge, which is like a clear or whitish goo in your undies. That usually starts a few months before your first period, but it can also get heavier right before your period starts.

The real way you know it's actually your period is when you see blood. It usually starts as light spotting, like a few drops, and then can get heavier. It's not usually a huge gush all at once, so don't worry about that! Just make sure you have some period products ready, like pads, just in case.

If you want to check out some more signs and get a general idea of when your first period might arrive, there's a quick quiz on this site: how close is my first period?
