At yesterday's ET, I received a more detailed explanation of our fert report. Of the 28 eggs retrieved, 21 were immature. Of the 7 mature eggs, 4 fertilized and grew well. Not a bad fertilization percentage, but it appears we should either have waited another day before the trigger or given my body a few more hours between trigger and retrieval. The doctor who did the transfer was more in favor of increasing the trigger-retrieval interval, which kind of scares me... if it's off by even the smallest margin, the whole cycle could be destroyed by ovulation. I read in someone else's blog about an embryology lab that tries to mature eggs in vitro. I should have asked her about that, and I'll certainly do some online research if we should need another cycle. In any case, as I said to her yesterday, it's all moot because this cycle IS going to work.
Our four mature, fertilized embies looked great. We had one 4-cell with no fragmentation, two 4-cell embies with minimal fragmentation, and a 2-cell with minimal fragmentation. Assisted hatching was done to all four of them to promote implantation. Now we wait. Beta is schedule for June 3rd, but I'll POAS on 5/31, at 10DP2DT. I got my +HPT 9DP3DT, so that shouldn't be too early. Here goes the TWW!
