The gynecologist is there to help you. If they are not there to help you, then who is. They deal with hundreds or thousands of cases every year some far worse than yours. THe worst thing that you can do is be too embarassed to go to the doctor. Doctor's are not supposed to tell anybody either, what happens between you and your doctor is completely confidential.
If you believe it to be a yeast infection which it may be, then you can also go on a good diet, get the right probiotics, and you will recover faster. Even if you're on antifungals from the doctor, I would recommend taking probacto's probiotics, it's helped me tremendously.
