Nub theory-is there even a nub??

[Seacrown]

Hi all,
Just had a 13 week scan and was hoping to be able to guess gender using nub theory. Love our picture so much, but I can’t see a nub? Can anyone else or is it just far more sensible to wait a few more weeks ? Thanks in advance if anyone can help out!!!

I think I can see it and looks like a boy.

Have you got facebook? Strictly nub theory have a fabulous success rate if so xx

Ahh thank you ! I’ll have a look on there. I thought I knew what to look for and now feel a bit baffled! Thank you for looking x
