Vaginal discharge is fluid—usually white or clear—that comes out of the vagina. Most women have vaginal discharge. Some women have discharge every day, while other women only have discharge occasionally. If the discharge changes color, smells different, or gets heavier, then you may have a problem such as an infection.
The amount and consistency of vaginal discharge changes at different points in a woman’s menstrual cycle. Increased vaginal discharge can be caused by normal menstrual cycle changes, vaginal infection, or cancer (rare). If a woman has more than her usual amount of vaginal discharge, she may need to see her healthcare provider. Source: hhs.gov
