When should I contact my doctor?

How long after TTC would you make an appt with your doctor to look into it?? We've been trying for about 6 months and I'm not even sure I'm ovulating. I've been using OPKs for the past 2 months and never get a positive. A coworker told me her doctor wouldn't prescribe anything until after a year but maybe it's different depending on the doctor? Do y'all have any experience with this?
