Why do we have a period

Okay so basically, having a period is how your body gets ready to have a baby, even if you're not planning that right now. It's totally normal and a really important part of growing up.

Every month, your body builds up a soft, cushiony lining in your uterus. This lining is like a super comfy bed, just in case a fertilized egg (which could turn into a baby) needs a place to hang out. Your ovaries release an egg, and if that egg doesn't get fertilized, your body doesn't need that comfy bed anymore.

So, when the egg isn't fertilized, your body just sheds that lining. That shedding is what we call a period! It's usually a mix of blood and tissue, and it comes out through your vagina. Then, after your period ends, the whole process starts all over again for the next month. It's wild, right?
