Hi Purple,
Yes, I had low progesteron on all of my pregnancies but my first one, which was seven years ago. My miscarriages were not due to progesterone but contributed I am sure. My last pregnancy, which ended in the birth of my daughter in January, I also had low progesteron. I was put on a progesteron pill (used as a suppository), for three months and after that all was well.
Take care,
Barbi
