Low progesterone and clomid

Has anyone got any experience with low progesterone after clomid? I took 100mg last month and cd21 progesterone was 5.4 this month I took 150mg and it was 0.6. My ob wants me to see a specialist now, but I still have refills for my clomid so I was thinking about using them and after I ovulate using progesterone cream. I wanted to see if anyone else has done that. I was testing and got positive OPKs last month and this month.
