I've never heard of it. What is it?
I had a straight nub which indicates a girl but I'm defo having a little man!! So I don't think its 100% accurate, but its good for a guess lol
oooh.. mind of i have a peek? according to the nub theory mines a girl and im on team yellow lol so id like to wipe all hope of the nub theory being right as apparently ive got 'the perfect girly nub'
Brilliant! are you hoping for a girl?
