Progesterone level???

Hayley

I am 5 weeks and just left my 1st doc appointment. They called and said my progesterone levels were a 9.1 and are calling me in supplements to take. They warned me that the supplements might not stop me from miscarrying. I’ve had miscarriages in the past and I’m so scared now. I need help, advice. Is 9.1 low?? Where should it be!?
