Nub Theory Gender???

[bl20]

Hi

Just been for my 13 weeks scan today and i'm trying to work out possible gender based on the nub theory. I know it isn't always reliable but it would be nice to have an idea of what gender the baby maybe. Does anyone have any ideas of gender based on the scan photo??? Thankyou in advance 😊

I’d say the sex is a boy.

I think boy too

Can't make out the nub, but skull looks like my DD so going to say girl
