Low progesterone, BFP

Shelby

I’ve been taking letrozole to help ovulation. I’ve been getting my progesterone checked on CD 21. This cycle, my progesterone was at a 7.7 at 6 dpo. The doctor assumed I did not ovulate and was going to up my meds next cycle. However, I’m now 13 dpo with a BFP! Do you think this progesterone number from my day 21 draw could hurt anything? I’m worried.
