Clomid Round 3...any success stories?

[TeaPotts]

DH and I have been TTC for 13 months now, but I have PCOS and don't ovulate on my own. I started Clomid in October, and am on CD14 of my third round.
Round 1: 50mg 3-7, O'd CD 20. 7 day LP.
Round 2: 100mg 5-9, no O, low progesterone.
Round 3: 150mg 5-9, currently on CD 14 with no ovary 'chatter' yet.

Any success stories or suggestions? I plan to use progesterone cream after O, but I'm not feeling very confident that O will even happen this cycle.
