Skull Theory... Girl?

[tatis81]

This is our scan from 13 weeks. We both thought this looked like a boy but after reading about skull fun theory we are inclined that it's a girl.

We could be wrong so calling opinions, guesses, experience for the gender game. What do other mums and mums to be think?

Maybe a girly nub, not sure

I agree, nub looks girly although not the clearest shot.
