What is the white stuff that comes out of a woman?

The white discharge that can come from a woman is typically cervical mucus, which varies in consistency and amount throughout the menstrual cycle. It can also be a sign of normal vaginal lubrication or, in some cases, an indication of an infection, such as a yeast infection or bacterial vaginosis. If the discharge has an unusual odor, color, or causes discomfort, it may be advisable to consult a healthcare professional.
