Does the top one look boyish?
Baby had his/her legs crossed the entire time, and kept bringing it up to their chest... also the angle wasn't quite right so it was hard to see a nub and I can't be definite I saw one at all during the scan (saw it so easily with DS) although it looks like there might be a nub in these pictures.
