Hello: Friday I had my 1st ultrasound and baby measured 8w3d which I expected (they estimated 9 weeks) but I have a 32-33 day cycle. The place I went to (doc send out for ultrasounds) seemed pretty advanced and they did the ultrasound vaginally and from my stomach. You could obviously see more vaginally. They did a 4D at this early stage and it was awesome. He said to come back between 12 and 13 weeks and he can tell me gender. Is that to soon? Or are they really that advance now? My doctor told me he's very good and that all his boy are boys and very rarely a girl will become a boy but that he's right on his stuff. So...anyone else find out sex between 12 and 13 weeks?
