Pregnancy progesterone level

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
I have this topic on here but want to be a little more specific. I am now 5wks pregnant. I had my progesterone level checked at 4 wks 3 days pregnant and it came back at 9.3. From everything I have read this is low, but my dr said it was ok. She didn't even want to test my level but I insisted. 
​My last pregnancy in March ended in a miscarriage and I have PCOS  which I have also read is common to have low progesterone levels. I am concerned I don't want to lose this baby as well. Any suggestions?
