What does “vaginal discharge cleanliness grade III” mean for pregnant women?

“Vaginal discharge cleanliness grade III” in pregnant women typically indicates poor vaginal hygiene and suggests the presence of gynecological inflammation—such as vaginitis. Vaginal discharge cleanliness reflects the condition of a woman’s vaginal secretions. Normally, vaginal discharge is colorless, odorless, transparent, and resembles egg-white in consistency with noticeable elasticity (i.e., “stringy”). When pregnant women develop various gynecological conditions, their vaginal discharge may turn yellow, contain blood streaks, or emit an unpleasant odor. The degree of abnormality in vaginal discharge can thus be assessed based on its cleanliness grade.

Vaginal discharge examination generally classifies cleanliness into four grades, with grades I and II considered normal. Grade I indicates relatively clean vaginal discharge with minimal cellular debris. Grade II denotes slightly increased numbers of white blood cells but still within acceptable limits. Grade III signifies a higher presence of both mixed bacteria and white blood cells in the discharge, indicating the onset of mild gynecological inflammation. Grade IV—characterized by abundant mixed bacteria and white blood cells—suggests severe gynecological inflammation requiring prompt medical treatment.

Gynecological inflammation during pregnancy is relatively common, primarily due to decreased immune resistance and hormonal fluctuations—especially elevated estrogen levels—which lead to increased vaginal discharge and subsequent changes in discharge cleanliness.
