What’s the earliest you can find out gender?

What’s the earliest you can find out gender through ultrasound? Tomorrow I will be 16weeks but my doctor doesn’t tell you the gender until 18-20 weeks. I really wanna know the gender now so I booked a private scan which I’ll be 16w4d when I go do you think they’ll be able to tell me the correct gender or see it yet?
