Frustrated

Please tell me that some people are as frustrated as I am. My husband and I have been having unprotected sex for the last ten months in my fertile window usually every other day, but make it especially a point when I’m ovulating. I’ve used prenatals, OPKS, and preseed. I’ve had regular cycles 27-29 days. No birth control for over 4 years. My ob gyn refuses to see me until May. I just can’t take it anymore!
