Ideally, we want the embryos to be nice, expanded blastocysts before they're biopsied so you can get a really clear distinction between what will be baby and what will be placenta so Dr. D and the embryologist have opted to let them grow another day. It occurred to me after the phone call that we also did our retrieval a lot later this time, several hours later than our first one, so these embryos are actually a little younger on day 5. They might have been nice blasts if they were checked in the evening instead of the morning so I'm staying positive and not getting discouraged.
I'm also pretty sure that if they were going to arrest they would have done so already, but I'm not ready to celebrate just yet. They still need to clear this last hurdle though I'm really optimistic now that they can do it. Grow embies, grow!
