We've been TTC for baby #2 for 21 cycles now with no success. I saw my OB after cycle 16 and she told me to wait 6 more months because I had been nursing for the first 12 cycles. Now I'm back to see her next week. What questions should I ask? Is there anything I should prep before hand to get the most action out of this appointment?

Things I have:
opk testing for ~7 months
temping for ~3 months
record of length of all 21 cycles (27 days +/- 2 days)
tested thyroid, testosterone, and prolactin levels (all normal)
