I had an ultrasound today at 14 weeks 2 days. I asked my doctor what she would guess and she said girl that she didn't see any boy parts. I had a big ultrasound right after and at first the u/s tech said girl then she thought maybe boy. I'm confused because when I look at the ultrasound of my 2 boys it's clearly boys. This one there's a nub but there's like white lines below the nub which my two boys did not have . What would you guess?
