Did you take the Baby Gender Prediction test? The one where you pee in a cup and swirl it around and do some other things? Its like 40 bucks or something
If you did dont trust it. My wife took it and said we were having a girl, Not true we are having a boy.
My sister in-law took it and it said girl, Not true she is having a boy also.
Just dont go out buying boys stuff until your for sure.
Congrats on the baby either way.
