Hello, ladies! I got my ultrasound at 13 weeks and 6 days last week and the tech said she thought boy, but didn't sound too sure of herself. She didn't go by the nub to guess either, she went from a top view of a potty shot, which I saw nothing. I've read about the nub theory but I've also read about that white line going through the nub. I think my baby's white line looks pretty parallel to the spine, making me think girl. But What is that bump on top of the line that is pointing up?? that is the only thing that has me thinking boy. It's been driving me crazyyy and any guesses would be awesome Pleaseeee if you know anything about this take a guess for me and let me know your opinions. THANK YOU P.S. I also have another shot that makes me think girl. I'll post both pics.
