Progesterone

I just got the results of my 7dpo progesterone blood test today and I'm conflicted.

7.6 ng/mL

So my doctor was wrong about me being anovulatory ... but it's on the low end to sustain pregnancy isn't it?

I confirmed my O with opk, cm and temping and went 8 days after my peak lh surge.

Should I be concerned?? If I was to start a progesterone supplement, at 8dpo today isn't it too late this cycle or would I do that after I get a bfp. I'm researching, but so many contradictory things out there.

Some would call then level normal and some would say it was insufficient ovulation.

Can you help me ladies? 🥺🥺🥺🥺🥺
