I have. really not that bad. make sure your hair is not more than a quarter inch long but make sure it's not just stubble either. exfoliate before going. and go to a place that specializes in waxing. there's always groupons for great places for cheap. it doesn't not hurt but it doesn't hurt that bad at all. also after you go once the redness subsides, exfoliate the next day with some apricot scrub and a loofah.
you get used to it kind of like a tattoo after the first few mins. but beware, my Dr told me you're not supposed to shave or wax down there at alllllll from 34 weeks on in case of labor because it can lead to infection! I'd wait til babys out, I know a lot of girls are self conscious about laboring with a bush lol but honestly don't be, it's better than struggling to keep it clean amidst potentially exposing baby when they come out. good luck girl!
