12 weeks yeast infection!

Does anybody know what I can use for a yeast infection?

I’m 12 weeks and I seen a lot of people saying “ask your doctor” but my appointment isn’t until THREE weeks away and it’s not easy to get in touch w my doctor. The nurses are BITCHES. And act like they can’t help you with anything. So when I come here for answers it’s because I’ve already tried to ask my doctor and i need a SAFE answer.
