Many possible causes: There are many causes of vaginal discharge, including pregnancy, miscarriage, hormone issues, foreign bodies (e.g. a forgotten tampon), and several infections, including STDs (gonorrhea, chlamydia, trichomonas) and non-STD infections like yeast and bacterial vaginosis. Any new or abnormal vaginal discharge should be professionally evaluated. Your topic tags show STDs are on your mind; get tested.
