Hi, Past, during your menstrual month, you either have menstrual fluid (red), cervical mucus (milky and thin), or eggwhite cervical mucus (clear and thick), that can come out of your vagina. Days 1-4 or 1-5, would be your period, then would come cervical mucus every day after that, maybe a half teaspoon or teaspoon per day, which is thin and milky and dries either light yellow-green or white in your underwear. Then around day 12 to 14 or so, would come eggwhite cervical mucus, which is thick and stretchy (like raw eggwhite) and so clear you could read a newspaper through it. That is a signal of upcoming ovulation (the clear mucus provides a path for sperm to swim up). After you ovulate, after about day 15 your mucus either goes back to the thin milky kind, or it subsides, until your next period comes at day 28 or 29. You might have seen either kind of cervical mucus coming out, especially at age 14, your system will be working very well. You can wear a thin minipad if it bothers you.
If you have thick white cottage-cheese type of discharge, especially if it's smelly like cheese, that could be a yeast infection. But it wouldn't be drippy like you describe.
I might add, it's normal to have this type of secretion; they are sterile and keep your vagina clean and balanced. Don't let any douche commercial make you feel like you need to try to wash it away, it's nature's way to keep you healthy.
It's just discharge. it happens to a lot of women. I wouldn't worry about it
