3 lines or "hamburger sign"

Hey ladies, I just finished reading a post saying that it is in fact possible to mistake genders when going by the three line rule. Here is the only gender shot I got when I went for my gender ultrasound (16 weeks, 3 days) and because LO was not moving their little hand from their privates the tech was only able to get this shot. She pointed out the 3 lines or the "hamburger sign" and she said she was 99% sure it was a girl. I don't want to start buying anything because at this point I don't even know if my baby is in fact a girl or not. I put arrows where you see LOs umbilical cord and also another arrow pointing at the 3 little lines. I sure would appreciate any feedback you ladies may have. ☺️
