I have thin white discharge sometimes dark yellow with bubbly areas & it sometimes be creamy yellowish greenish with fishy odor no itching or burning?

New discharge: Suspect bacterial vaginosis. The discharge is often off-white and thin; the odor is an unpleasant "fishy smell" that may be more noticeable after sexual intercourse and during menses. Only a third of non-pregnant women improve without treatment. See your physician for quick exam and testing to confirm. Treatment involves oral or topical antibiotics.
