Boy or girl? For a friend

Its a 16 weeks ultrasound.


I am also pregnant, after a loss (16 weeks, because of heart defects), but I know mines a girl :)

Thank you for your time :)

Maybe girl.

Thanks, anyone else?

I say maybe girl too.

Thank you.
Is it very difficult to see, since its maybe?
I think I can see the nub?

Maybe girl from me too. I do see the nub it's just I don't think the full nub is pictured.

I'm not seeing anything clear for 16 weeks.
