13 week scan - can anyone see a nub?? (just for fun)

[HelloGumdrop]

Had my 1st scan this week at 13 weeks and just for fun thought I'd see what the Nub Theory was all about

But I don't think I understand it at all haha and not really sure what I'd be looking for anyway! Where is the nub? Is there one in these pics? Is my child nub-less?? Should I be worried?!

I can’t see the nub - sorry. Do you have any other pics where it might be clearer?

Haha sadly not!! Thanks for the message though, it helps to know that someone else can't see any nub. At least I know I'm not missing something obvious!
