PCOS or Endo

I think I have endometriosis or PCOS or something and I have brought this up to two primary care doctors. They only say “every woman is different” and just switch me to different birth control pills. I don’t want to have to keep jumping from office to office but I want to get actually checked out because my husband and I have been trying to conceive for a few months now and I need to know what I’m up against I guess. I need a referral for my insurance for the specialty clinics and I just am not sure what else to do? Has anyone else gone through this?
