Progesterone and HCG


What are/were your levels at 6weeks? Doctor just called and said my progesterone is 15.7 and hcg 5605. I have had 3 miscarriages due to low progesterone and am on a daily progesterone pill. But i am curious as to what is considered “low” progesterone?

The doctor did say as long as it’s above 10 you should be good?
