Yellow/green/white colored vaginal discharge. a bit thicker than normal. normal smell and no other symptoms. what is it?

STD check needed: Colored (yellow, green, beige) discharge suggests infection, including STDs like gonorrhea or chlamydia, assuming you are sexually active. Possibly a vaginal infection like trichomonas or bacterial vaginosis, but 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.
