10 week u/s- Guesses?

So I did PGD/IVF and supposedly put back 2 girls, but of course I know that isn't a 100% certainty. I had an elective ultrasound today at 10w1d and the tech made her guesses. HRs were 176 (baby A) and 171 (baby B). Based on that the tech was calling them girls. However, she thought she saw a boy nub on baby B so she changed her guess. She said she didn't see any nub on Baby A though so she still thought it was a girl. These are the two pix she showed me (baby A again might not have any nub but baby B this is where she thought she saw a nub). I know it is still really early to be making nub guesses, but what do y'all think?

I think I am going to agree with your technician (not so much on the HR side of things) but twin B looks to have a boyish angle to the nub, a fork can be seen though, and from what I can see of twin A I would at this stage think girl - though isn't 10 weeks a bit early for a guess?

Beautiful bubba pics :baby:

Your too early for nubs. I am sure they are girls :) They do have different shaped heads.... I 100% don't believe in the skull theory so I would be confident they are your daughters in there!!

I would definitely trust pgd more than a 10 week nub guess--congrats on the great u/s:)
