Ultrasound

Went in for anatomy scan at 19 weeks exactly. The tech was having a lot of issues getting baby to cooperate she had me leave come back after 30 minutes and a soda. She still was struggling then said well best we are going to get I cant get leg out of way so we are going with girl.... moments before that ot looked like boy bits but she couldn't confirm. I see three lines but had also saw what looked like a penis moments before she got frustrated and called it. Opinions??
