Is it weird to take a bath on your period?

I always do it and didn't know it wasn't normal until all my friends told me I'm nasty for doing it. Of course I clean up everything down there before I get in and then the bleeding stops in the water, so I don't get what's so gross about it? Obviously if I started bleeding I'd get out bc I'm not tryna bathe in my own blood. It helps with my cramps a lot. Does anyone else take baths on their period or am I crazy 😂
