Nubs and skulls!! Please help, so many mixed reviews

Hi mummys, we desperately tried to sway blue this time. I've had
So many mixed reviews with this nub. 50/50. I don't know what to look for at all since my
Two daughters honestly showed no nubs at all in their ultrasounds.the only one who showed anything at 12 weeks was two thin straight lines poking out of a profile shot, nothing like this thick fork.
I've included a picture too of their three heads (the middle and the right are my two daughters and the left is the newbie). As you can see the girls are identical and the newbie is a different shape so I'm hoping this might give us blue hope. Thanks!!

Ps. Some extra info!! This shot was 12 weeks, 5 days (bub was measuring ahead as we thought it was only 12w 2 days) Attachment 25808 this is also another head shot incase the skull theory helps?

Attachment 25816 This is another shot I found of te newbie at the nuchal scan. Don't know how reliable these will be as obviously you can't tell if the back is rolled... But they look very opposite - I see a "dome" below the nub in the left shot which is apparently boy related I read... But the shot on the right doesn't even have a fork so I can't tell what's what if someone could help me. Thoughts would be really appreciated! Totally doing my head in over this (very happy to have a healthy baby though overall but one can always gender dream)

I haven't had experience with a forked nub, thought they meant a girl? My boy bubs always poked up with a bulb at the end. I'd say girl based on this

Thanks! I think I'm probably grasping at straws. I've heard both boys and girls can have forks (apparently it's just trickery with the ultraskund screen?)

It's looking like a boy from the first picture (angled nub)

Thanks for the input bunnywabbit! You've given me a little ray of hope :cheerteam:

I would also guess boy from the first image it's a little bulby on the end and shorter than most nubs that look girly. It's not certain of course but as a fellow blue swayer I truly hope you get your little boy!! GL !!

Anyone else?

True Blue! Thank you so much for your positive input. My fingers and toes are crossed for you! I hope we both get our healthy little blue bundles :)

Bump!!

I would also guess boy. Good luck :-)

Nub looks boyish to me!

Boyish looking nub
Both girls and boys can have a fork looking nub

Guessing boy, but not very sure. Skull looks different from sisters at least. FX for you!

My guess would be a boy, based on the angled nub on the first pic. My fingers are crossed for you! xx

Its a hard guess but dont know y my instinct feeling abt this is boy ... hope u hear blue :)

Thank you SO much for all your guesses! Fingers crossed I hear blue! And for any other swayers, I hope you get your pink and blue bundles x

I think it's blue too although I'm not an experienced nub guesser!

It's pretty angled. Boy guess here! Good luck!

Thinking blue. FX.

boy and a very classic caveman boy skull
