Just had my first scan at 13+5 weeks and it's my first pregnancy :)
My sister told me about the nub theory and is predicting a girl! I've had a feeling for a while it's a girl and although my partner wants a boy, at the scan he said he feels it's a girl also.
I wouldn't even have noticed that white thing if my sister hadn't have mentioned it, yet it's so obvious now I see it! I was too busy studying the face!
Wondered what your predictions are? And how many of you have found nub theory to be accurate?
