Hi ladies, I hope its OK for me to jump in here. I'm a little ahead of most of you cause I had my FET yesterday. Reading through your posts I noticed you all have the same concerns and questions I had.
This is my first FET and is a medicated cyce. We had 4 6 day blasts frozen, 2 of really good quality and 2 of good quality. Our RE orginally said he recommended thawing all 4 and transferring the best 3. My DH and I don't feel we could discard one so we were planning on re-freezing the 4th. I was SOOOOO scared that none would survive the thaw. On top of this my lining hasn't been co-operating, it measured just 6.9mm one week prior to the transfer and my RE recommended cancelling the cycle. After some thought and several good reasons we decided to go ahead cause my lining never got to more than 8mm last time either.
Anyway, yesterday was our day and the good news is all 4 survived. #1 was hatching and 100% of the cells survive, #2 was hatching and 95% of cells survived, #3 not yet hatching but 90% of cells survivied, #4 not hatching and 75% of cells survived. The RE saif anything greater than 70% cell survival is good. We asked if we could refreeze the 4th one and transfer 3 but he said the 4th wouldn't survive another freeze and thaw. So, we transfered all 4. I'm not sure if he allowed this just because my lining is a little thin and wants to maximize our chances but I'm not complaining. the chances of quads are slim. I'd be happy with whatever....1,2, 3 or 4
although, I have to admit, 4 sounds scary.
My test date is next sunday. I wanted to just chip in here for some inspiration on the survival of frozen embies. I was so worried and doubtful cause I have come to expect the worst but was pleasantly surprised. Thats an understatement......we are ecstatic at the survival rate.
Good luck to all of you
Nikki
