How do you work out a NUB theory? Pic attached

[Shookethtothecore]

Hello,
13 weeks today, reading about NUB theories and trying to make head or tail of this one. I realise it’s not accurate and just a bit of fun but anyone have my ideas?!

I think there's a 50% chance it's a boy.

Congratulations though

Well @kaytee87 I'd say 50% chance girl.

I could guess that 🙈 I was wondering if anyone had understood the nub theory and could see where it was on this one?!

I don’t understand NUB theory, but this scan is definitely if a girl if that helps for comparison?

Thank you, and congratulations. I can’t work it out either 😂

You haven't got a true midline image so you can't see it.

Ahhhh right! Thank you for explaining that

This pic gives you a good idea of what you are looking for at 12 weeks. Boys in front, girls down. But if the scan isn't taken in the midline you won't see either.

I'm guessing boy
