Chapter 2: What Different Colors and Textures May Mean
The color and consistency of vaginal discharge can provide useful clues, although they cannot establish a diagnosis by themselves.
Clear or white discharge: This is often normal, particularly when there is no unpleasant smell, itching, or irritation. The amount may increase around ovulation, during pregnancy, or with hormonal changes.
Creamy or pale yellow discharge: Discharge can look slightly yellow after drying on underwear. If it has no unusual odor and causes no discomfort, this may simply reflect normal secretions.
Thick, white discharge: White discharge that resembles cottage cheese and occurs with intense itching, redness, or soreness may be associated with a vaginal yeast infection. However, thickness alone does not confirm the diagnosis.
Gray or thin discharge: Thin grayish discharge accompanied by a noticeable fishy odor may be associated with bacterial vaginosis, a condition involving changes in the balance of vaginal bacteria.
Yellow or green discharge: Discharge that is distinctly yellow-green, especially when accompanied by odor, irritation, or pain, may indicate an infection, including certain sexually transmitted infections.
Brown or pink stains: These may represent small amounts of blood mixed with discharge. They can occur around menstruation, but persistent spotting, bleeding after sex, or bleeding after menopause should be medically assessed.

The most important consideration is the overall pattern. A familiar discharge that changes slightly during the menstrual cycle is different from a new, persistent change accompanied by discomfort.
