Now I'm no expect but this doesn't sound like a progesterone problem. Once you've ovulated your body starts producing progesterone in preparation to support a pregnancy, if pregnancy doesn't occur the progesterone drops and you start bleeding (so the drop in progesterone causes bleeding). If the baby passed before bleeding that would imply there was a chromosome or other problem. You're body then realising, dropped the progesterone so you could miscarry. There is debate as to whether progesterone dropping is the bodies way of ending a pregnancy that is not viable anyway... If you were miscarry ing and the first symptom were bleeding that would seem to me to indicate a progesterone problem or even chemical pregnancy due to lack of lining for proper implantation, but it sounds as though both pregnancies just weren't to be. As I said I'm no expert, just my analysis and thoughts! In any case I am deeply sorry for your losses and hope there are no more!!
