Its possible that you're seeing normal fluid of ovulation. By regularly, does it come for a few days every couple of weeks? If so, its probably part of your normal cycle.
If there is any itching or discomfort, it
could be a yeast infection.
Don't be embarrassed to go to a GYN. Believe me, you have nothing to be ashamed of, they deal with these things all the time--this is common in ALL women.

I just had an appointment with mine yesterday.
