Can the nub theory ever be wrong ? Help please!

We had our scan done yesterday at 13 weeks . I’ve only just seen about the nub theory !! Any guesses ? Those bits to me looked like boy bits but apparently it can be completely different

I don't think any method is ever 100% accurate. as my dad says the only way to know 100% is when baby's born.

I don't think its very reliable, but looks like a girl nub to me!

Looks like a to me. If I recall properly, the nub for a boy is more angled towards the top, more vertical. This nub looks very horizontal to me, like a girl.

Looks more girly to me too, nub theory is 85% with a perfect pic which I dont feel yours is, any more pics!
