Progesterone Levels Low

LeAnn
Hi all, I just found out I was pregnant Sunday and did first blood work Tuesday. My hcg level was 46, which seems fine according to the rule of doubling every 2 days, but my progesterone was 9.8. Anyone else had it this low this early and carried to term?  I'm getting on supplements tomorrow, but since I preciously miscarried on January 14th at about 7 1/2 weeks I'm a little worried. Any positive stories appreciated!
