Help with a tricky nub ❤️

Hi everyone

Yesterday I had my 12 week scan. It was see our little baby healthy and and having a good wriggle. 

Since we got home i can’t stop analysing my scan. Can anyone see a nub? I think I can but it’s blocked by the leg slightly.

if you can see it do we have any nub pros that can read it for me. Baby is very curved and I’m not sure where to measure the spine from. I will post some photos with arrows on to show you what I mean. 

Thanks in advance 

Laura
