Yeast infection?

So I've taken two diflucan pills over the last two weeks and I still feel like my yeast infection isn't gone. I went to the doctor and she said it was a yeast infection. But it just feels like I've had really rough sex. And I haven't. No itching. No burning. No discharge. No new partners been with the same man for two years. He's not having any issues. I'm about to go back to the doctor. This sucks a big one.
