Sweet.Bee, I concur with Kinza. Doctors can be very different. My OBGYN practically threw Clomid at me within the first couple of months of seeing him. Granted, we had technically been "trying" for a year (albeit loosely, with no charts, OPKs, etc.)
Hang in there. It may be just the thing for you, to get your cycle in order. But I will say that having a doctor who is cautious about prescribing C may be a blessing in disguise. It's not an easy drug for some (i.e., me). That said, if you feel like he's not being responsive to your concerns, it may be time to seek a 2nd opinion? How long until you hit the 1 year mark?
