I have 30 day regular periods, day 23 progesterone test only 0.58ng/ml this month. What should I do. I'm trying to conceive and also have cystic ovaries?

Fertility meds. Your progesterone level is very low which is a sign that you didn't ovulate this month. This goes along with having polycystic ovaries. I'm actually surprised that you have regular periods. It's possible that you will need fertility medications (such as Clomid (clomiphene) or Clomiphene) to help you ovulate better to speed up the time to conception. Doctor may need to give you progesterone to menstruate.
