Insurance help for infertility

I'm from North Carolina and me and my husband are trying to conceive. I am trying to find inusrance that can help with infertility. I have been diagnosed with PCOS and have tried femara to help with ovulation. We haven't been successful. We have no male factors. We are being referred to a fertility specialist and I know that it can get expensive. Any help will be appreciated.

TIA. (:
