Nub and/or skull theory

[Boymama85]

I’m 13+3 and had a scan today. Wondering if it’s clear to see a nub or tell by shape of skull whether it’s a boy or a girl.

Guesses welcome 😊

Thanks

I don't see a nub here, sorry.

No nub and i’m bad with guessing on skull

[Kelbear]

I can't see a nub either, sorry.

I’ve added the rest of the scans we got.

I have no idea what I’m looking for with the nub, can anyone see a nub in these?

Thanks for looking. 😊

Sorry I just can't guess on these, nothing to go on.
