Talked to the doctor today. His take was that this cycle could have gone either way, he wouldn't have been surprised if I had gotten pregnant, but given the odds of any cycle working he wasn't surprised it didn't work. He wants to change two things for next time: the protocol, and adding co-culture.
The protocol will go from 450 follisitim and 150 menopur way down to 150 follistim and 75 menopur, keeping the estrogen priming and adding clomid.
The co-culture is basically a study they're doing that seems to show that with fragile eggs, growing the embryos alongside uterine lining cells really helps protect the egg and speed up the cell division (since I had one 4-cell, that could be important).
Talked at length to my friend Jessica tonight who had 2 failed cycles before going to Cornell for this same diagnosis, and who now has 3 kid under 3 thanks to or doctor. She was able to answer some questions and basically provide a lot of moral support and encouragement, so I'm ready to get back on the wagon in January, or whenever I can. The lab shuts down for the holidays until mid-January, so I might or might not be able to start right away in January with the uterine biopsy and EP. Worst case is I do that in early-mid February, and stims late Feb-early March. If I'm really lucky some of this could fall over my February break from school.
