13+0 u/s pics -- skull theory guesses?

[MamaK4]

Any guesses on skull theory? No nub shot.

Tech said it's a girl based on a potty shot (which I didn't get a pic of), she said it is very flat and there would be a little something sticking out if it was a boy. Only 13 weeks though so I'm trying very hard not to get my hopes up!

Im interested in the skull Theory can you explain how a girl skull vs a boy skull look like?
