Maybe: You will ovulate 14 days from the length of your cycle. So with a 35-37 day cycle, i would expect you to ovulate on d 21-23. There are other ways to see if you ovulate- basal body temperatures, ovulation predictor kit, just getting a period means you ovulated. I do not check Progesterone to check ovulation in general. It sounds like you need to talk to your doctor.
