I have been tested on day 21 twice for progesterone levels to see if I actually ovulated and both tests came back at 16.1, my doc told me that anything over 20 is considered a successful ovulation anything under isn't! I've read on loads of places that anything above 10 is successful.  So why is my doc telling this? Is she wrong or what.  She said its determined on certain labs or something.  Am so confused!!! Can anybody give me some insight on this as I feel my doc of shit! She even went on Google in front of me to find out herself.  Please has anybody got any experience on this?
