They should DEFINITELY be writing you a prescription for many months (like, 12) at a time so that you can just call the pharmacy and get a refill. Its totally ridiculous to be calling the doctor every month, nevermind going in for a check up!!! I'd switch doctors or else just be really forceful about getting a longer prescription. Because...no one does that! EVERYONE writes multiple month long prescriptions for birth control, unless there is some kind of special issue.
