How do you tell if you have a period or a cut in your bum?

Okay, so period blood comes from your vagina, which is in the front, and a cut in your bum would be from, well, your bum. They are definitely in different places.

Period blood usually looks like dark red or brownish liquid, and it comes from inside your body. It will soak into your underwear or a pad. A cut on your bum might have bright red blood, and you'd probably feel where the cut is, like when you wipe, and the blood would be more like a smear on the outside.

If you're ever worried or confused about bleeding, it's always a good idea to tell a trusted grown-up. They can help you figure out what's going on and make sure you're okay.
