When I am menstruating and using a tampon, I notice when I pull the tampon out that the bottom half is soaked in urine. I urinate, then wipe, then remove my tampon, then wipe again. I have never had this problem before but now it happens every time. I have been using tampons for years and I'm using them correctly. Is there a possibility I'm "peeing" through my vagina? Would a prolapsed bladder cause this?
