Hi ladyrose! I'm another who has progesterone issues!
I've had 3 mc and 2 healthy babies. With this current pg I have been on 200mg of progesterone support. My hcg numbers weren't doubling quickly and my progesterone level got down to 32.8. I have also had varying amounts of bleeding between 6-14 weeks. My doctor was shocked that this pg is still viable given my history and the numbers but I am happy to shock him I am now 17 1/2 weeks!
The blood test to me means a quantative bhcg reading which is to see how much your levels have risen. I have everything crossed for you!!!
Much love xxx
