I have been having strange symptoms lately containing my vagina. I am always sure to clean myself thoughly down there but the other day i had a horrible fish smell that i have never had before. I fixed that by using yogurt. then now i have irregular bleeding. I had sex with my boyfriend then the next day i started bleeding. i thought it was just because of the sex but it has been going on for two days, like a full on period and my stomach hurt really bad today. the only thing is that i am on birthcontrol and shouldnt have my period for another week and a half? should i be concerned? should i go get a pap smear?
