Yes, we requested that they only thaw one blast. Actually, we had 3 frozen blasts, all stored in different straws, so they were able to only thaw one at a time. Our first choice embryo survived the thaw with 90% of the cells intact, so we still have two frozen embryos left. Hopefully, we will not need them if all goes well with this pregnancy. What I can tell you is that we knew we were only going to transfer one, so we had three chances at one of the embryos surviving the thaw. That made us feel better. Because of the way our embryos were stored, etc. the embryologist would have just gone from one to another, etc. should we have needed them. I can also tell you that the process and the medications for the FET are much easier on you than the fresh cycle. In fact, we asked our RE
if for some reason this FET didn't work how long we would have to wait to try again and he said that we could go right back into another cycle as soon as AF arrived. I hope this helps and best of luck to you.
