Talking to the Doc

SO and I have been trying and then trying/not preventing for about 16-17months now.  I haven't seen a doctor for any fertility stuff for a year... Last year I did one round of clomid and was over stimulated.. All I got out of that entire thing was a definitive diagnosis of PCOS. My cycles have stayed "normal" since then until now. I just had a 60-day cycle. So we are ready to go back the doctor and start really trying again. Anyone have any advice for what kinds of tests/procedures I should discuss with the doc??? I have looked up a few things, but I was just wondering what some others have been through.
