Progesterone level and TTC

Pretty confused... 
I'm VERY irregular. So much so that I went two years without a period before I am decided to ask for help. I'm currently seeing a fertility doctor. They put me on provera which gave me a period. I took 50mg of Clomid on period days 3-7. My period began on Feb 9. I thought I ovulated on Feb 24. Had unprotected sex. March 3 my nurse asked me to come in so she can do bloodwork. The next day she calls and said I did not ovulate. My progesterone level was 0.84. I'm a little confused. I'll start a round of stronger Clomid once my period comes, but should I be on a progesterone medication?
