Hey there - I posted this in my post I'm really to your response but thought I'd make a separate post I'm case you didn't check back.
Thanks so much and I'm so sorry to hear you are going thru the same thing. This situation was not even on my radar! I thought either they stuck or they didn't. Not they stuck but one isn't doing well. And I NEVER in a million years would have guessed that one of the embryo's would split and that 2 would not be doing well. I'm honestly at this point just staying optimistic, that maybe it was too early or that somehow they were crowding each other out.
What was your dr's opinion on your situation?
You will be in my prayers and I wish you the best. Please let me know how it goes on Thursday.
