Clomid fail :(

I just started my first cycle of Clomid (50 mg) this month after 6 months of failing to ovulate on my own. I did not get a positive ovulation test from CD 5-23, but went for my progesterone blood draw on CD 22 as my doc requested.
The test came back today with a level of 1. I'm so disappointed. Last month, prior to the Clomid, I at least got a 6 on CD 21. 
My cycles run long, usually 33-39 days, but since my progesterone was only a 1 on CD 22, looks like no hope this month.
Any one else have a total first month fail on Clomid?
