Havent had my period in a month and i have a white discharge. help?

Sexually active? If : Yes - would take a pregnancy test. When pregnant, vaginal discharge is thin, white ; milky. But because this is not a diagnostic symptom, a pregnancy test should be taken if you miss your period. A clumpy (cottage cheese- like), white, non- odorous discharge associated w itching, burning, swelling or redness can be due to yeast infections.
