Healthy vaginal discharge, also called leukorrhea, is thin and clear or white and has only a mild odor. The volume of discharge increases throughout pregnancy to reduce the risk of vaginal and uterine infections. Discharge is at its most heavy in the final weeks of pregnancy, when it may contain pink mucus.
“It's what we always get asked about.” The extra discharge is due to a boost in estrogen production and increased blood flow early in pregnancy, she says. When normal, it should be somewhat thick, clear to white in color, and odorless.
Changes in vaginal discharge can begin as early as one to two weeks after conception, even before you've missed your period. As your pregnancy progresses, this discharge usually becomes more noticeable, and it's heaviest at the end of your pregnancy. You may want to wear an unscented panty liner.
