Nub theory - can anyone see anything?

[MrSpock]

15 weeks, dichorionic twins. I asked if they could tell what they were but the babies weren’t in a good position. I thought I briefly saw something but the pictures are unclear.

Can anyone work out anything from these?

Anyone?

Sorry, pretty sure you can’t see the nub in either of those pictures.

I didn’t think you could either, but I’m rubbish at these so thought I’d ask anyway!

We are having trouble with names so it’d help greatly if we knew, that way we could focus our efforts lol

I know the feeling. We have 2 boys and have used our favourite names - if dc3 turns out to be a boy we are buggered!
