Yeast Infections

So this past year it seems I've been getting yeast infections almost monthly. My husband is growing frustrated because that means I don't want to have sex (It's painful!) All I ask is that he give me about 3 days for the diflucan to kick in but he gets soo pissy! Then I feel like a bad wife and I don't think I should feel that way. Like maybe he should be a bit more supportive and caring towards me. I don't know what to do anymore. I don't want to keep getting into arguments every month about this.
