Bei Bei that level is a little low but it does show ovulation.

Clomid can be a really effective treatment for low progesterone levels. *Most* women report higher prog. levels on clomid. Some women have symptoms. Like Debbie I don't have any (maybe a bit crankier - hard to tell!) problematic symptoms. Many women don't. It is unfortunate for those who do as it is a really effective treatment.

Stillhoping that prog.level is indicative of the follicular stage of your cycle (the stage prior to ovulation) are you sure you didn't have it a bit early?
My first round of clomid my cd21 test was only 15 indicating that ovulation had not yet occured. I knew I hadn't yet had an LH surge as I was using opk's. I was retested on cd28 and my prog was 60. This is not uncommon. Unless you are having follicular scanning or doing opk's it can through a bit of a spanner in the works.

ETA: I have just realised that the low level was when you weren't on clomid sorry Still HOping...
