Gender ultrasound at 15 weeks?

Ha

I found out with my second baby at 16 weeks along. It was very obvious that he was a boy. The private ultrasound lady was very thorough and checked multiple times. Well this pregnancy she wants us to come in at 15 weeks & 2 days. Is this too soon? I know she will check multiple times and if she isn’t sure she will let us come back for another scan. But has anyone found out this early? Bonus points if you have a gender shot around that week.
