I have yellow and brown discharge going on for weeks now. it doesn't hurt, but today i got bleeding only from one side of vagina(period?)normal?

Infection? STD?: Any abnormal vaginal bleeding and any new or abnormal vaginal discharge should be professionally evaluated -- and you have both. Colored vaginal discharge usually means an infection -- depending on your age and sexual risks, STDs like gonorrhea, chlamydia, or trichomonas are often the most likely causes. See a doctor soon. Good luck!
