How long did you TTC before starting clomid?

Andrea
My husband and I haven't used any prevention since we got married 2yrs ago. We weren't "trying" to get pregnant at first we just figured if it happened we were ready. But now that we are actually trying....nothing. We've both seen Dr's. Things are good on his end and my Dr doesn't seem overly concerned but I've had an appointment set up for end of July if we don't end up pregnant before then. So I plan on bringing up clomid but how long is long enough to start it?
