Hi
Long time lurker but first time posting. I'd never heard of nub theory until reading about it on here. Although I can't figure out what the nub is in my own 12 week scan photos to have a guess!
We're planning to find out at our 20 week scan but hoping for some guesses to keep me going for the next 7-8 weeks! From looking at previous threads there are some nub experts kicking around these boards. I promise to come back and confirm who was right!
