13w 4d ultrasound nub theory/gender prediction please :)

What do you guys think baby is going by skull/nub theory?

I've posted this on two different sites just to see what peoples guesses are. One site they all say boys and other site they all say girl! So I'm totally confused!! lol

My first guess would have been boy! :D

They are actually two different pictures but they both look the same! I've tried to get a good shot of each pic twice using my phone, but it's difficult.

Boy!! :) There seems to be a boy angled nub above the main flat white line :)

Hi, is it any of these parts of circled? Because I'm not sure if either of those are correct lol Not exactly sure which part to look at. I'm going by both of them haha.

I would say it's circled green. Not good at nub theory but the skull looks kinda girly.

For 13 weeks I say girl

Boy
