I found a really cool website today, but I'm positive not everyone is going to be as excited about it as I am. Don't say I didn't warn you!
It's a website with photos of one woman's cervix - one photo for every day of her cycle. If that grosses you out, don't follow the link. If not, here you go: beautiful cervix project
(Oh, and let's not be rude: I found this via A Doula Too.)
