Were Yu having a boy or girl?
He will still be here at that time but it will be very stressful because we will be packing and moving everything into storage, but I guess finding out my little girl is.really a little boy would be even more stressful, because I will be out buying stuff as soon as they tell me! :P
I did it at 16 weeks and it was an awesome experience. Go for it. defiantly not a waste of time.
The farther u are the easier it is to tell... if u get it too early, u may be given the wrong gender.. is it possible u can do it at like 16-17 weeks??
