Update to nub or tailbone - any new guesses?

[Perfect3]

Hi all. So I studied up on ultrasound pictures before my scan but apparently I still have no idea what I'm doing. :) Is this a nub or the tail bone or what? I would LOVE any guesses on nub or skull! I'm 12w 3d but I measured 12w 5d. Thoughts??

Skull maybe looks boy to me? I can't see a nub but I'm not so good at knowing what to look for yet!

Thanks for guessing! I have no idea, I see two lines but I'm not sure if that's a nub. It's much clearer in my actual picture...
