First appointment jitters

My husband and I have been ttc #1 for about 18 months now with zero luck. I was diagnosed with pcos about 6 months ago and have been on metformin since. We have also done 2 cycles of femara at my obgyns office. Neither cycle resulted in a large follicle. I had lots of follicles but all stay around 9mm. After the second  cycle, my dr decided to refer me to a local RE. My first appointment is this Friday and I am so nervous! My husbands sperm analysis came back with good prognosis so I really believe most of our problems is the anovulation. Anyone else going through a similar situation?? Any tips on preparing for the first appt?? What should I expect??? I'm excited to know answers but terrified it's going to be horrible news!!!!
