The history and findings on physical examination in women with vaginitis are relatively nonspecific. Nevertheless, certain features often suggest a particular diagnosis , which should be confirmed in the office by microscopic examination of vaginal secretions and, if necessary, culture. Trichomonas is classically associated with a greenish-yellow purulent discharge; candidiasis with a thick, white, adherent, cottage cheese-like discharge; and bacterial vaginosis with a thin, homogeneous, fishy smelling gray discharge. However, the appearance of the discharge is unreliable and should never form the basis for diagnosis. you need to go to gynaecologist coz it can coz ascending infection and reach your baby....... take care
