I had my NT scan done on Thursday at 11 weeks 3 days. The tech/doctor looked at the angle of the nub (not the nub itself) and said they were 90% sure it was a girl. I have 2 boys so, of course, I'd love to have a girl but don't want to get my hopes up so early on. I find out for sure next week through the Panorama test. But just wondering if anyone else was given such a certain guess based off nub theory? And was it correct?
