I just asked them to give me their best guess. Both times I was told a boy and both times they seemed VERY sure. Still I am not going out and buying blue. Still going to wait until my 20 week u/s then compare again. I asked over a week ago at my NT scan which was done in a different location then today I had one because I was having spotting last night. I asked after they looked to make sure everything was ok. They also said both times that I am measuring a week ahead so my ticker says 13 weeks but they say 14. When the baby cooperated and let us see between the legs we all saw a definite boy. The tech even said it's definitely a boy. I saw what looked like a regular uncircumcised penis hanging there (TMI). So just tell them to take a guess, but don't take it to the bank just yet.

My doctor guessed girl at my 12 week scan, but told me it was only a guess (he said 60/40 girl). I have my anatomy scan at 17.5 weeks when they will hopefully tell for sure.
I had my NT scan done last week and the tech and the OB stated that it's a girl. They are 95% sure. They are the only facility in the area (Childrens Hospital) that has the most up-to-date equipment to be able to tell the sex. According to their track record, it's very good. However, I am a realist and always have doubts. DH thinks it's a girl and he has thought so all along..he wants a girl more than a boy.
Re: How many of you have already found out the sex??

The accuracy stats are at the bottom (basically no better than a guess at 12 weeks)
