Most girls notice a yellow or white stain on their underwear after they go through puberty. This is a normal fluid that helps clean and moisten your vagina. You’re completely healthy and normal if your discharge is cloudy white, has no odor or has a slightly salty odor, increases in amount and becomes “stringy” (similar to egg whites) during the middle of your menstrual cycle when you are ovulating.
If you find that your normal discharge is annoying, you can wear panty liners/shields on your underwear. Also, to keep your vaginal discharge under control, make sure you wear cotton underwear (which absorbs moisture and lets air circulate). Take daily showers or baths and make sure that you wash outside your vaginal area every day with mild soap, and then rinse and dry yourself. Don’t use deodorized panty liners or deodorant sprays in your vaginal area.
If your discharge changes, it may be a sign that you have a vaginal infection and you need to see your health care provider.
