Nub theory anyone got an idea?

[Kerry539]

Hi I've heard of the nub theory but don't have a clue what I'm looking for or if you can even see it in my photos. If anyone can please tell me what you think.
Thanks

Hard to say for sure without being able to enlarge pic, but looks flat from what I can see!

If you push the picture it should enlarge. But only the bottom one seems to work for me. I can see the white lines but wasn't sure if that was the nub. So excited as I'm hoping for a girl!! But will be happy either way 😊
