Abnormal discharge may look yellowish, greenish, or grayish-white in colour. Changes in consistency is also a symptom. For instance, sometimes cottage cheese-like discharge is a sign of an infection.
Normal or healthy vaginal discharge is typically clear or whitish in colour and does not have any smell or odour. Vaginal discharge is your vagina's way of cleansing and helps keep infections and germs at bay.
If you notice anything unusual such as change in colour, texture, amount and smell - it could be abnormal vaginal discharge. If your discharge smells bad but not fishy, it could be a yeast infection.
