FINALLY! An Appointment with gyno June 14th, what should I expect?

Ive been TTC since August of 2009. In october 2010 I seeked my primacy care doctor to put in a referrel for me to see a fertility specialist. I have a period every month, just never the same amount of days apart. My husband has a daughter from the past, so of course I blamed myself for us not conceiving. well, I FINALLY FINALLY FINALLY (sorry I'm really excited LOL) got an appointment made. I am military, so the referrel process with our insurance takes FOREVER. Its an appointment I have been looking forward to for SOOOOO long, but I fear I am to excited for it, like I am going to be dissappointed. Its been almost two years, I am ready to subject my body to any testing known to man, regardless of pain. Pain is only temporary, and I am willing to go through anything to become pregnant. What should I expect her (yes, I made sure I got a female doc lol) to do at the appointment? I've always done papsmears with my regular doctor and I've never seen a gyno for fertility issues. What is your experiences? My insurance covers ANY diagnostic testing, as well as clomid, injectibles, hsg's, etc. It does not cover actual IVF, or IUI which I am not wanting to do anyways due to my husband's religious background. I have taken 2 cycles of clomid, and it made me VERY moody and my uterus lining became too thin. Can I insist on no more clomid and move on to injectables?
