Is this a nub?! If so any guesses?

[Aismixx]

Looking back at a private scan we had at 11w 6d and seen a lil something.. not sure if it's a leg or nub.

We have never been able to get a proper picture of little one as I am as incapable of drinking water as little one is at keeping still.

Just for fun guesses if so.

On reflection I think it's a leg 😞

I uploaded this to a nub theory site and they came back with a skull theory instead that we are having a boy!
