Low progesterone 7dpo

I got my 7dpo progesterone back today and it was 8.3 mg/mL. I know that’s low. I feel so defeated as I was really expecting something higher with all of my lifestyle changes.

I have one LC and two losses afterwards. If I were 3dpo I’d start supplementing now but I’m not sure what the next steps are for this cycle.

Anyone have any thoughts?
