Finding the gender at 15 weeks?

Gerycah

I got my ultrasound tomorrow, I'll be 15w2d, the dr said I'll be able to find our the gender then, I thlught you couldn't find the gender until 16-20 weeks. I know every baby grow at it own pace, may i see y'all ultrasounds around 15 weeks? I do have a back up ob, doing another ultrasound at 16weeks, as a aecond opionipn.
