I have been on Letrozole for 3 months now. My progesterone level has skyrocketed each month. I know progesterone isn't really an early indicator of pregnancy but I am now 3 days late and not sure if its because of my REALLY high level from cd 21 or something more. I'm terrified because I miscarried May 2019 and my progesterone was SUPER low the whole time...like never made it about 13 in my whole 11 weeks. This month my cd21 blood work came back as 31.5!! I'm just nervous and looking for reassurance.
