Seems like it might make more sense to do a 3dt if there's only one or one good one and one questionable one?
Either way, good luck and I hope you make it to ET and that one sticks!
I know... I've been fighting with myself over this one. By the way the lab lady sounded, I think the questionable one isn't with us anymore. I was so shocked when she called that I forgot to ask. I just heard the words "we had to thaw the very last one" and my brain kind of gave up on me... I'm calling them tomorrow and check on how the embie is doing. I'm so afraid of losing this one too, that I might go there tomorrow and force them to do the transfer. If it doesn't stick at least it will have cuddled for a bit in me.
Good luck on your coming cycle!
