Nub Theory Guess?

[CurlyMama25]

For fun, if anyone is clued up on nub theory I'd love to hear what you think.

My first (ever) dating scan today was followed up by bloods and several instances of passing out and not feeling quite right yet, need a distraction!

My guts been saying girl, but my head boy (other than me, only boys in my and my partners siblings)...

TIA!

Can't see a nub but, just for fun, I'd say boy 💙 based on skull theory

Thanks,

Think it might be visible on this one but not sure what I'm looking for!

I can't tell sorry, too blurry and hard to tell what's umbilical cord, leg etc.
I'd still say boy from that second pic too though
