My cervix is closed but i have a lot of discharge?

Pregnant?: I assume you are pregnant if you say your cervix is closed. Pregnancy can cause a thin, white, milky, mild smelling discharge, and this is normal. Not normal discharge would be green or yellow, strong smelling, and/or accompanied by redness or itching. This could be a yeast infection or it could be an std. Blood should always be reported. Get checked by your doctor to find out the cause.
