This is my girl I was scared it was a boy since it was so swollen but I went for my 20 week scan and she's still a girl lol

This is exactly what happened with me today. I'm 18+3, baby had its legs crossed and this is very similar to what I saw on the screen. She said that the clitoris on girls can swell up and stick out and I thought if it was a penis it'd be sticking out a little more then it was. Without seeing the balls she wasn't comfortable saying either way. It's super disappointing since who knows when I'll get another scan(my Dr thinks I will have one at some point), I'm thinking yours (and mine), could be boys but its really difficult to say.
