I waxed for a long time and found it to be WAY more painful when I was pregnant, especially after about 30 weeks. The area is much more sensitive and has increased blood flow, so it really is much more painful. If you were already doing it regularly and it was something you wanted to maintain now, I'd say it might be worth the extra pain, but if it's your first time (which ALWAYS hurts the WORST anyway), I wouldn't advise it.
