ERA results

I got the results of my ERA and it showed that I need about 12 additional hours on progesterone for my ideal receptivity. I’m thinking this may be why I miscarried two times on my own because all other tests show nothing. My first FET is scheduled for December 21st. Did anyone have success when changing their exposure time to progesterone after an ERA?

Also, I am terrified of ovulating on my own, is this common? I didn’t do birth control at the beginning of this cycle because we were trying to get the transfer done before they close for the holidays. Nurse said I might ovulate and now I’m so concerned!

Thank you!!
