Help Please

We have been TTC since January 2015, i went to my old OB around August 2015 and they drew blood. I was told i was annovulatory and they put me on Letrozole for January February and March 2016 with no results. I stopped taking any medications until May 2017, they didn't do anymore test but prescribed clomid. We got a BFP that month but MC two days later. I waited for 3 months before the doctor put me back on clomid for September, October, and November 2017. He also put me on progestrone supositories but i only took them September and October because they made me insane. I never got another BFP after the first one and haven't taken anything since then. I refused to go back to that OB but had to wait to get a refferal to go to a new OB. I have FINALLY recieved it and am going to see my new OB next month. What test should i expect her to do? And what questions should i make sure to ask? My mind blanks when I'm sitting in the Dr office. Thanks for any advice!
