Nub theory wrong?

[Cassvi]

Hi I’m just wondering has anybody had mainly boy guesses Or “leans” as they say in the Facebook group from the nub But then it turned out to be a girl? I’ve had mainly boy guesses and a few girl but I have a gut feeling it’s going to be a girl!

I had 95% tell me girl, asked a lot of opinions and its a boy! X

Well this gives me hope haha

If they are leaning boy there must be something about the nub that is rising slightly (like it does with a boy) but if they aren’t sure the gestation is too early or the photo is not clear enough. They’re normally pretty accurate on those Facebook groups though but not always. They guessed right on there with my boy. What were you hoping for?

Hoping for a a girl! They all said that they were just leaving I think cause it was a bit too early I’ll post some photos!

I'm by no means an expert but, from my understanding, if it's before 12+5 it's not that accurate.
I think if the nub is pointing up or rising, there's less chance of it coming back down but if it's flat then it's got a chance to change. So more chance of girl guesses becoming a boy rather than the other way round (does that make sense?).
It's just a guessing game anyway, I wouldn't pin too much on it.
