1. Wash the underwear immediately and don’t leave it for washing the next day. 2. You can wear panty liners to prevent the stain. 3. Soak your underwear in cold water for a few hours and then wash; hot water allows the stain to settle.
Remember, the normal vaginal discharge is milky and does not have an unpleasant smell; it is subtle. In case there is an infection lookout for these signs: 1.
