4 days late. After progesterone cycle

Kelly
Last month I used progesterone to start. I don't know why the doc put me on it. I always have a cycle at some point in the month. Sometimes early. I even started in the middle of the progesterone. Now I'm 4 days late for this cycle. Did an hpt first day. Bfn. I can't start my clomid until I have a cycle. What now?
