Can you see girly lines on a 15 week frontal shot?

First I'm sorry I don't have any pics. This was an er u/s so I didn't get any. Anyway the tech was measuring baby's femur but it was from the front or top view instead of a potty shot. I did see what appeared to be girly looking lines but would they be visible at 15 weeks from that angle? I'm not sure if it could have been cord insertion but the lines were very short so I'm guessing probably not cord. Anyone have any thoughts or pics of 15 week frontal shot of girls? Or anyone have pics of cord insertion so I can compare?

Cord looks like 3 lines that are fuzzy light gray floating out from the baby.

Ok tat's what I was thinking. These lines were pretty bright and white and looked to be up against baby that's why I was thinking either girly parts or where the cord inserted but I couldn't really tell if it was right up in between the legs or more towards tummy. I'm thinking probably girl though.
