Boy with 3 lines?

Hi mamas. Hubs and I are really confused on the sex of our baby. We told the tech we didn’t want her telling us what it was but that we wanted to see a bum shot. Well at first we were pretty excited because we thought we seen balls. And then she wiggles her wand and 3 clear lines came into view. Now we have no idea lol It was clearly 3 lines but also sticking out more then girl scans that I’ve seen. Can a boy have 3 lines? Or was it a swollen girl? Does anyone have pictures of their boys at 20 weeks exactly as well as a swollen girl so I can kinda see how it all looks?
