Infertility ob appt 4/1

Hubby and I have been ttc for a little over 3 years now, had a d & c on 1/30/15 and going to my ob on 4/1/15 to start infertility medicine. I'm just wondering what to expect? I've gotten to the point where I've given up, so my expectations are pretty low. Can anyone tell me what to kind of expect?
