I've been on depo-provera for 2 1/2 months and each time i have sex i use wipes to clean up , can that increase the chances of pregnancy ? or is it bad at all

Protection still ok: The contraceptive (pregnancy preventing) effects of depo-provera are not changed, regardless of how a woman cleans up after sex. "use wipes to clean up" means different things to different people, so as long as one is not irritating her bottom by overdoing the clean-up, "wipes" should be fine. If the semen is leading to vaginal symptoms, then using condoms should solve those problems.
