Help me find the nub? And what do you think?

[beansprout55]

As the title suggests. Can you see the nub? Scan 13+3

Hi circled in yellow I think… but I’m no expert! If you are looking for a gender guess I would go girl as the nub looks horizontal to the spine. There are some really good (free) Facebook groups that could help if you wanted x

I say girl.

I've just looked through my other scan photos taken on the same day and one is a very very obvious nub which looks totally different!! I agreed girl but now I'm wondering boy! See photo attached
