Now I'm confused

After Friday's news about my estradiol levels dropping and my LH and progesterone elevating, along with sky high BBT temps over the weekend, I went into ultrasound and bloodwork #4 (CD18) pretty much assuming that it was only a formality, as I had clearly ovulated a sub-par follie on Friday.

Well, the moral of this story is that my body is completely unpredictable. Immediately jumping out on Rightie were two nice follies, one at 21mm and one at 16.5mm. Anything 14mm or larger can contain a mature egg but REs like to see 18mm or larger on a medicated cycle. As they grow 1-2mm per day, even the 16.5 should get there tomorrow.

I'm so confused. Clearly it looks like I ovulated on Friday, and I know you can obviously ovulate more than one follie per cycle -- but can it be 3-5 days apart?? My brain hurts. I'll have to wait to hear from the nurse this afternoon on the RE's plan and my bloodwork. I'm not getting my hopes up, but I'm hoping they at least let me do an IUI to pass that final insurance hurdle for IVF. I figure cautious pessimism might work better for me than cautious optimism.
