My Day 21 progesterone was 30nmol/L (9.4nm/ml when converted this ng/ml unit).

Some google articles say u need > 25 nmol to confirm ovulation.

Another article says it has to be >32 to provide adequate environment for implementation. Any pregnant with this level?

Anyone needed progesterone treatment for similar level?

(GP didn’t say nothing. He says, try for few 12 months , if no results then ill refer you to fertility specialist. )
