OK, sure I know it is the broken down uterin wall. But I mean, is it actually just normal blood? What is it that builds up? And could you test what blood type you are from using that blood? I know it's a weird question and could be a really dense one... but I am just a bit confused. Serious answers are appreciated, if you think I'm being stupid, just move on.
