Vaginal discharge is a normal bodily function that helps keep the vagina clean and prevent infection. It is a clear or whitish fluid that comes out of the vagina and is produced by the uterus, cervix, and vagina. The amount, consistency, color, and smell of vaginal discharge can vary depending on factors such as menstrual cycle, sexual activity, and birth control. Normal vaginal discharge is usually clear or white, and its thickness may change throughout the menstrual cycle. Thick, white discharge is common at the end of the menstrual cycle, and it is not accompanied by itching. However, if itching is present, thick white discharge may indicate a yeast infection. As long as the milky white discharge does not have an odor and there are no other symptoms, it is most likely a sign of typical vaginal health. If the color of the discharge develops a white-gray shade and a strong fishy odor, it may be a sign of an infection. Other types of abnormal vaginal discharge that may indicate an infection or other problem include yellow or green discharge, clumpy discharge, discharge with a bad odor, and bloody discharge. If you experience any of these symptoms, it is important to see a healthcare provider for diagnosis and treatment.
