Help for nub theory!

[FirstTimer07]

Hi,
Had my 12w scan yesterday for dc 2 and I am fascinated by this nub theory but have no idea what the nub is etc
Could anyone explain it for me or like to guess the gender from the pics?
I'm feeling very sick today so thought it could be a bit of fun to cheer myself up!
Thanks lovelies

Looks like a girl to me, straight and flat.

Thank you! What exactly are you looking at tho?! Anyone else any guesses?!

Girl.

Oh my goodness that would be lovely as have ds1! I still don't know what you are all see8ng tho! Fascinating hearing guesses! X

The nub is the bit that they can catch on a picture if one leg is down.
If the nub is laying horizontally, it suggests a girl. If it points up to the sky a little, it suggests a boy.
I've cropped your second picture- the brighter straight bit in between leg is the nub. It's laying flat and the skull is girl shaped.
Of course, it's no guarantee, more speculation but it's fun to guess!

Thank you so much for explaining it to me. I so wonder if it is a girl now. My sickness has been awful this time and had none at all with ds1 so who knows! Thank you!

I'm saying girl x
