Nub theory at 12 weeks! 💙💗

Breezy❤️
I accidentally posted this somewhere else and couldn't figure out how to delete it. 😕
Anyways! 
I'm DYINNNGG to know! 
Any guesses on nub theory on this ultrasound? I'm including the one from 11 weeks and 12 weeks because I'm not really sure if I can even see a nub, lol. 
(all for fun of course... it'll be loved regardless. 😊) 
These two are from 12 weeks 3 days. (Not sure if there's even a nub?)
This one is from 11 weeks 3 days.
