i thought i should mention this, because when it first happened to me i freaking flipped out!
if you are a return ana you might already know this but if your new, itl jump you. after a while eating pro ana, your periods will stop. you might start flipping out thinking you maybe got pregers or something--YOU DIDNT! this is just your body preserving all the iron in your body, once you start fasting/cutting back, your body wont be able to give stuff away so easily. this does not mean you cant have children!!!!!! i know people who have missed periods for up to a year, once they start eating again, the peroids will come back!!!!! but, if you miss periods for a long long time, there is a big chance you cant have kids, and a big chance of miscarages.
just thought i should let you know because when this happened to me i had no clue what to think(im still a virgan so....). ~E
