7dpo progesterone levels good or bad?!

aloha7

My progesterone level at 7dpo was 27 nmol/L (7.8ng/ml).. is this number good enough to sustain a pregnancy .. like pregnancy can occur with that level or is it too low? I know it means i ovulated but im trying to understand if i need progesterone supplementation for the next cycle (if this one didnt work).

thank you!
