I have brown stuff coming from my vagina and my mom says i get it from her and its feom having sex without a condom how do i get it to go away?

Go to doctor: It is unlikely that the brown discharge is related to your mother. It might be related to unsafe sex or maybe just old blood from a prior menstrual cycle. I advise you to go to a gyn or planned parenthood to have an std checkup and pregnancy test and see if you are a candidate for the hpv vaccine. Having sex without a condom is high risk.
