i'm 17 , i got the drop provera shot , and i kind of think that's the cause because my body is not use to the bacteria , and i haven't got my period at all since i've got the shot . i've never had a bad smelling vagina , i wash really well , and it usually has no scent .. i don't have any weird colored discharge, no bumps , no itching, no signs of a STD , but i am sexually active with no protection , with the same guy ( 2 years together ). has any one else ever experienced this ? it's not a yeast infection because like i said there are no other side effects besides the smell , no chunky discharge , no white discharge , just clear discharge and a weird vaginal smell . it's been smelling this way for a week exactly now .. it's like a fish smelly , but then it's like a chemical like smell , or musty .. i can't describe it but it's unpleasant.. I repeat there are no signs of a STD .. IF YOURE READING THIS PLEASE SAY SOMETHING .
