My husband and I just started TTC #1 in July 2012 and I started seeing an RE this month because I just turned 38. We think I ovulated on cd 12/13 and my blood drawn (today) on cd 20. My progesterone results were 16.2 and she wants me to start 100mg a day of progesterone starting today. Are my results low? When I looked it up I found that anything above 10 is normal. I'm extremely sensitive to all meds and couldn't even take birth control pills because of the hormones and I'm scared to take anything that's not totally necessary. If you've had yours tested what were they and what did your doctor recommend?
