Brazilian wax.

Haley
So I'm 35 weeks & im about to make my appointment to get my first Brazilian wax. I haven't been able to see my vag since December and I'm tired of being "patchy" 
I'm not even having a vaginal birth but I'm already gonna feel so gross the first few weeks after c section I think it will be nice to not have to worry about trying to squat to shave.. But I'm really nervous. Anyone have any tips on how to make it go pretty smooth ?  What should I expect ?
