Dying to Find out Gender!!! How early did you go? and How accurate was it?

Ai
Ladies!! So I would love to find out my baby's gender before 20 weeks. My bestfriend and cousin is already planning a gender reveal and I would love to do at at the end of July. I am currently 13+6 and wants to know by 16 wks! Please recommend me to a good place in Michigan with 2D, 3D, and 4D scans. Thanks!!
