Danni, totally normal!! With DS we were told at 22wks it was a boy, he was a flasher. I worried the whole time though! And when he was born (I am so embarrassed to admit this, and still laugh at myself...) the very first thing I said when he slid out was "is it still a boy???" LOL like I thought he would change?? not "is the baby ok?" or anything, I just wanted to know the sex!!! Don't worry, it will all be fine!!
