Elective 3-D ultrasound for gender @ 14/15wks?

Alison • Mama to two amazing boys and baby girl on the way!
The elective ultrasound office by our house said they can tell as early as 14 weeks, has anyone had a successful gender confirmation that early? Or at 15weeks? I did it at 16 weeks with my son, didn't know you could do it sooner at the time. Would love to know sooner than later but didn't know if it'd even be accurate at 14wks.
