Gender Ultrasound At 16 weeks?

Jacquelyn
Has anybody had their gender ultrasound at 16 weeks? I have 2 boys, and I had both their gender ultrasounds at 20weeks. My OB says it maybe too early to do the gender ultrasound but I can do it and see. But I see some people have had it done and it's confirmed for sure what their having and not a mistake. Just don't want to get the ultrasound done and they tell me oh it's a girl, then, later on in the pregnancy say oops it's a boy. Any suggestions?
