Gender ultrasound

Marcy

So I had an appointment a couple weeks ago whenever I was 14 weeks pregnant. I thought it was a little early for the doctor to say she was putting in the order for my anatomy ultrasound but the scheduling department called me and scheduled my ultrasound for when I will be 17 weeks 3 days. Will this be too early to see the gender? Or should I be fine because it’s close enough to 18 weeks?
