I had an u/s at 15 weeks to peak at the babys sex. it was a whopping not even 2 minute peak. she said that it still was pretty early but she is leaning towards a girl. she said that it can take up to 19 weeks for testies to drop. Has anyone had an ealy u/s and was told girl and at your 20 week+ u/s found out it was a boy? In my siggy, you can see why i am rooting for boy.
