For the past few few days I've had a watery discharge from my vagina. I have to wear a pad. It's almost like I've peed myself. It started after my period and I always douche after my period or else I get a bad smell. This discharge I'm having isn't fishy, it smells like feet or homeless person, maybe a little like poop. I've tested positive for hpv in the past so I'm scared it cancer.
