High progesterone levels good or bad??

Sarah

This is my first cycle in letrozole. Had my serum progesterone test done on day 21 of my cycle. It was 29.5. Nurse said that was good. But I wanna know... is it good that it’s that high? I’m dying to test, but don’t want to test too early and be disappointed! I’m on day 23 now. 9 DPO. 6 days before my period is due.
