Low Progesterone

My bloodwork last month showed my levels were low (ended up getting my period 4 days early). I ovulated on Sunday, so I go for more bloodwork next Monday. I'm 2dpo & am feeling crampy - I'm so worried this is a symptom & this bloodwork will show the levels are still low. Tried Clomid this month - I was hoping it would be our cure. I'm not feeling too hopeful since cramping usually means AF is on her way. :(
