Yes, I hit the jackpot first go - however I did ovulate on the clomid later than usual (which is an abberation), however it was effective at increasing my prog.levels (they were 60 at 7 dpo).
I took 50mgs (lowest dose) of clomid from cd2-cd6. I received a positive opk on cd20 so we are assuming I ovulated on cd21.

I hope this helps!
