Ok so i posted my gender scan, but iv never really took much notice of nub theory etc as never heard or read much about it, I cant see a nub in my photos but tbh i have no idea what im looking for :) So guesses welcome if you can see anything, i was measuring 12+6 but was 12+2

I really can't tell because the leg could be blocking. Sorry.

Maybe :XX: ( based on 2nd pic)

Not sure, going to guess boy.

No nub seen. Guessing boy based on skull (which is totally not accurate :)

Maybe girl

maybe a girl?

can't tell, sorry,
