After the 20 week scan my son was not convinced that they were having a girl...he said the radiographer/ultrasound tech. didn't seem or look positive that the baby is a girl since the baby was not in a great position at the time. They waited another month (as recommended by Bellisimo, where she had it done) to get a 3d scan. We all went last night and she is defiantly a she, we could clearly see! Her name is Kara and she is adorable.
