Nub theory

[Sha1234]

Hello All,
I posted my 12w+4days scan on a lot of FB groups and ALL said clear boy based on nub theory. I even got 99% boy from early glimpse. Yesterday, I went for my 20 week anomaly scan and she told me it's a girl!! Although I'm extremely thankful that my baby was healthy but I cannot control my emotion that I was expecting a boy and now I have a feeling like I lost my boy:( I attached the images. Any idea?

The nub definitely looks like a boy and if they're hiding, boys can be mistaken for girls more than the other way around. If you can, get a private scan for double reassurance.

Yes, that really looks like a boy. Unless that's not the nub but something else! The one time a family member got told wrong was when they were told they were having a boy but she was having a girl (girls can be swollen so perhaps this was the case).

The sonographer showed me three lines and said it's a girl but before checking for gender she told me they baby has crossed her legs. What's the chance that she was wrong about these three lines? I cannot stop thinking about it! :(
