me and my friend convinced a girl that when you get your period, blood comes out of your belly button and that's where you put a tampon or cover it with a pad.
A childhood belief about periods

others believed things like this

- I used to think that if i touched my belly button it would unfold and my belly would be inside out forever. Anon
- HA! I used to think when you got your period, you would just pee blood...I wish it was like that...if only.Anon
- I used to believe period blood came from the nipples. I thought that was what "padded bras" were for!!Anon
