Nub theory guesses anyone?

[nsprongs]

I told myself I wouldn't do this but here I am! Any guesses?

Ooh depending on gestation (above 12wks but less than 15wks), I’d guess you’ve got yourself a little boy nub there 💙

I thought it was a girl based on the theory 🙊

I can't see a nub but on the skull theory I would say girl.

Yes I thought girl too!!
