I am sorry for your losses, mama. The thing about low progesterone, it could have been low because you were miscarrying instead of the cause of the miscarriage. I would definitely start charting to see if you have an LP defect. In the case of an LP defect using progesterone does help, but there are mixed feelings about whether is actually helps in other cases. My current OB will only prescribe it for an LP defect or fertility cases.
