There is a theory that Dr. Peter Eckhart of Women's Therapeutic Institute (makers of Progestelle) is actually some kind of marketing pseudonym. I have no idea if that's true, but I choose to imagine that this is his work uniform:

Testing progesterone levels

I haven't heard one way or another whether it's useful to track your progesterone with bloodwork, but I've compiled a list of progesterone blood test providers if you're curious to know your levels. It runs in the $50-$200 range depending on which company you order the test from.
