I used to believe that you got periods through your belly button, I got images of women on the beach, with blood poring from their belly buttons!
I have no idea where I got this idea from!
I used to wonder how you used to get tampons in your belly button, I even tried this once when I was ten, only to realise this wasn't possible!
