Can you predict my first period based on my birthdate and symptoms like mood swings, tummy cramps, and feeling weird in my stomach?

Okay, so like, I can't actually predict your exact first period date just from your birthdate and symptoms, because everyone's body is different and moves on its own schedule. But I can tell you that mood swings and tummy cramps, and that weird feeling in your stomach, are super common signs that your body is getting ready for your period. It's totally normal to feel like that!

Your first period usually shows up about two years after your breasts start to develop. And before that, lots of people notice a clear or whitish discharge in their underwear for about six months to a year. That's your body just cleaning itself out, no big deal. You might also have a growth spurt where you suddenly get taller.

Those tummy cramps you're feeling can be your uterus getting ready for action. And the mood swings are all thanks to your hormones, which are literally doing a wild dance party in your body right now. It gets real, I know.

Since you're noticing these signs, it means your body is definitely getting ready for big stuff! If you want to find out roughly when yours is coming, there's a quiz on this site: how close is my first period? — it takes like a minute.
