20 week scan . Boy or girl ?

I’m not sure if it is a girl since baby wouldn’t cooperate good and the doctor had to flip me to my side to look between the legs . I saw her struggling to get the gender. Since i was going to have a gender reveal I couldn’t see the screen to make sure. I can’t figure it out. With my other 3 girls there was 3 lines and it was much clearer.

Could it be wrong ?
