Hi Mai1974
this is a late reply. you've probably moved on since your last posting, maybe feeling a little less stressed. I am also doing ICSI, last transfer of fresh blast didn't take. Out of all fertilised eggs only one made it to blast. It's a tough business this growing to blast outside of your uterus. In normal conception from day 3 to 5 is when the cells move from the fallopian tube to the uterus and so in the lab the culturing technique has to be perfect for it to survive. They actually have to take it out of the culture it was in till day 3 and put it in a new culture til day 5 or 6. I had one that made it and 4 that almost did.

I am going to try another round aiming for a blast as that is what the clinic believes best and I guess I'll give it one more go and after that if I loose them all again, I will demand day three transfers from then on. I got one blast out of five eggs, so next round of harvesting if I am using stronger med's I hoepfully might make up to ten and then maybe I might get 2 blasts. The survival rate is really small, you have to be prepared to risk losing them. I hadn't expected it and was devastated.

It is hard to know what is best, trust your instincts. You can always try again, seek other opinions. Good luck, hang in there!!!!
