So, in the wake of my second cancellation... no change of plan.
I call with CD1 for another baseline.
Based on the series of progesterone levels they took, the clinic believes I ovulated maybe the day before I got my period last week. They tried to tell me that it was "dysfunctional uterine bleeding" and not a period, but I'm not buying that. They think I'll get my period next week. I'm betting on early in the second week of October, because that would be the absolute worst possible timing for me to be out of work for retrieval later that month (and right on schedule according to my iPhone).
