Thick white discharge means what?

Thick white discharge during pregnancy is completely normal. It is because of increased estrogen production and greater blood flow to the vaginal area. This discharge is made up of secretions from the cervix and vagina, old cells from the walls of the vagina, and normal bacterial flora from the vagina. If the discharge has an odor and color I'd recommend seeing your doctor.

If you are not pregnant then it could be yeast infection or leukorrhea - the odorless or mild-smelling milky discharge. !
