How for sure I’m having a boy ??

So this was when I was 20 weeks and 2 days I just wanna know if this is a for sure boy because for me the private part of my baby looks pretty big or maybe zoomed in too much. I guess I’m just trying to make sure super happy this is my first baby boy. 💖💙

He was moving so much and the tech said he wasn’t showing so that’s why I’m kinda freaking out.
