I had three miscarriages & suspecting it’s low progesterone. Any experience ladies?

This is my January month and progesterone checked on the 13th was 1.3. My period that month was about a week late but it’s irregular from my miscarriages.

I just miscarried this week & my ob told me supplements prior my bfp wasn’t necessary but I feel and even felt at the time it was. (My progesterone this pregnancy was 12, last miscarriage was 8.5 & they didn’t run progesterone check my first miscarriage)
