How to get rid of a yeast infection at 8 weeks prego?

I am exactly 8 weeks and have a yeast infection I've had it for about 1 1/2 week- 2 weeks. I have the burning during sex, burning while peeing, itching, chunky discharge but my obgyn nor any other Doctor will prescribe anything for me and told me not to use anything over the counter until I'm 14 weeks they said it's not safe until 14 weeks pregnant. I'm pretty miserable it's only getting worse. Any suggestions??
