How soon did you find baby’s gender

Okay I know it maybe too early too tell but I went for my first ultrasound today and the ultrasound tech said my baby was very wiggly as I could see too wouldn’t stop moving lol so you know they measure and look at the baby from different angles... well the baby kept crossing and uncrossing its legs and opening them and I didn’t see any sign of a penis could it be a possibility of a girl anyone had this happen?? I’m 14weeks tomorrow
