Baby with it's bum in the air! nub guesses anyone please?

During my 12 week u/s the baby had it's bum up in the air. Can anyone tell me how this affects the nub? I can imagine my little one's nub to be very flat if it's spine was straight, Ultrasound was done at 12+4 but measuring 12 exactly. (sorry it's only a faint nub as it's hiding behind the leg) TIA

I don't see a nub in this image.

It's very faint and just above the dotted line. I saw it during the ultrasound or i wouldn't have noticed it myself!

I see what you're looking at but I think that is part of the pelvic bone structure and not a nub.

Sorry can't see a nub

dont see any gender clues here, sorry hun

It's definitely a nub because i saw it very clear during the ultrasound. I know it isn't the clearest so thank you for looking

Bump

i dont think thats a nub though, if it was i would say ....but again im not thinking thats the nub....good luck!
