Girl ????

So I had an ultrasound last night, and we did see between the legs, there was nothing sticking out, and honestly they looked like girl parts. The lady performing the ultrasound didn't say anything about the gender, but I do know what girl parts look like, lol. There was three lines. I was 13+6 but baby was measuring 14+4. With my ultrasound, everyone says I'm having a girl. The head is perfectly round, and honestly, it just looks like a girl ultrasound. Even though the lady at the ultrasound didn't say anything about the gender, is it safe to say I'm having a girl ?
