Provera

I had a miscarriage + D+C in February this year. Since then, my cycles have been erratic and ranging from 33-47 days long.

My doc put me on provera. She said I should take it on the same day every month and I just started it on Sunday. According to the glow app and my past periods, I won’t ovulate for three more days.

Is it even possible to ovulate if I’ve started provera? Should I have waited to take provera until my period was later than usual?

Has anyone else ovulated or gotten pregnant while on provera?
