Im not an expert and your pic seems to be upside down so it is hard to really see....
But I had my anatomy scan at 19 wks 2days this past week and she showed us a potty shot on the screen and it was on a very new machine... (the ones that go between 2d and 3d).... so maybe mine was clearer because of that BUT my little boy that is cookin his potty shot at the same gestation was like HELLO i am a BOY. The penis protruded a lot and it was very clear something was poking out.
IDK if I see that in your pic. But then again I am not an expert and your pic is upside down,
