Is this the nub? Have a guess at the gender please!!!

Hello Everyone!

Proud Dad to be here... my wife doesn't want to know the gender, and although I also don't want to know for sure, I am curious to try and have a guess from our ultrasound. I'm particularly interested in the 'nub theory'.

Please see our ultrasound pic below... I only read about this theory yesterday so I dont really know what i'm looking for yet, and I suspect that its not really clear from the pic, but I circled what I think may be the nub and am I correct in thinking if the theory is true then we could be having a baby girl??? I have attached both ultrasound pics, the original and the one where I circled it.

Opinions please! Thanks!

Hi :) That doesn't look like the nub to me. Do you have any other pics? What gestation was baby dated at scan?

No nub visible here sorry
