So... My GYN's nurse FINALLY called me back and was given permission to tell me the results. My 6DPO progesterone was NORMAL at 12!! However, it was down to 6 by 7DPO, and I started my AF 2 days later. It was actually a relatively long LP and cycle for me, and the first time I Oed since December. So, with the confirmation that I did in fact O, I suspect the 8-day weird gushy AF this cycle was possibly because of a VERY short-lived CP.

So, my P levels are at least good for a few days post-O on the rare cycle that I actually O.
