Hi All

I am confused about the role of progesterone. I had a BT done 14DPO and 16DPO and my prog was 28 nmol/L and then 30 nmol/L. From what I read online, this is barely ovulatory, let alone early pregnancy. I have found tables that ask for the minimum in pregnancy to be 30 nmol/L (equiv to 9 ng/ml) but really desire the levels to be at least at 50 nmol/L by 14DPO. One article said that 30 is ovulatory (at 14DPO), 70 is the average for women who go on to have a miscarriage and 200 is the average for successful pregnancies. Now I am concerned that I am going to have an inevitable miscarriage.

hcg at 14 and 16 DPO was 56 and 190 respectively.

Has anyone had such low levels at 14DPO (not at 7DPO checking for ovulation) and gone on to have a successful birth?
