STD check needed: In sexually active women, colored (yellow, green, brown) vaginal discharge suggests infection, including STDs like gonorrhea or chlamydia. Possibly a vaginal infection like trichomonas or bacterial vaginosis; these usually cause odor. Get examined and tested ASAP, either with your doctor, your local health department STD clinic, or a reproductive health clinic like Planned Parenthood. Good luck!
