Our donor was seen at St. Mungo's today, and she had 35+ follicles, with the largest measuring 14-21mm in size. (Obviously not all of these follicles will have eggs/mature eggs in them, but our nurse said "this is a great number to have prior to egg retrieval.") Her estrogen level was "solid" (1509--anyone know if that's good?), and Dr. Dumbledore asked her to return on Sunday for another visit.
There is a good chance she will be triggered for egg retrieval on Sunday. If so, the retrieval would be on Tuesday, which is what we have been anticipating. I will have my final passing ultrasound at St. Mungo's the same morning, and MM will produce his "fresh sample." (We already have a sample cryopreserved, too, just in case.)
If the donor is not triggered Sunday, then she will return Monday for a visit, and her retrieval would be Wednesday. That will mean moving my appointment. The weekend nurse will update us after the donor's appointment on Sunday.
Either way, we will (we hope) have embryos growing in the St. Mungo's lab by next week! :-)
