Is this a boy?! Nub and skull theory, 12 weeks

Hi moms,
I'm postning this picture for a friend of mine!
What's your guess? :-) Is that the nub in the third picture?

Thanks!

Anyone else want to take a guess? :)

I would hazard a guess at blue but because of the angle of the pics I really am not too sure x

Pictures are at a bad angle. Can you lay them flat?
