When I got my 12 week (but actually 13 because I am a bit ahead of where we thought) scan, I was all pout pout sad sad because I couldn't see a nub anywhere and I wanted to try out the nub theory and SAD SAD SAD. Anyway, I was looking at my scans of my scans (SCAN OF A SCAN - INCEPTION!!!) and I think I found the nub. Attaching the original as well as a marked version that shows the angle of the dangle. If I'm right, I am having a little Derek! What do you guys think? Am I mistaking a leg for a nub or something or is it a little boy?
