FET #2: craziness ensues!

First off, I have been pretty horrible commenting this ICLW (and actually in general over the past few weeks). For someone reason, reading blogs lately has been stressing me out a little, so I apologize. I hope I will be back in full blog commenting gear soon.

Here is the craziness I shared with my message board buddies earlier today:

Yesterday was our 2nd FET. I was told to arrive at 10:30 am. When I arrived, the nurse told me that there were many transfers today and to expect a long wait. I figured I must be last on the list, because I noticed that they were having both the women who came in before me and the women who came in after me change into gowns but not me.

Around noon, Y decided to speak with the nurses and as usual, he got more information than me. They told him that it wasn't that I was last on the list, but that they were putting my transfer on hold because the thawing had been problematic and the lab was waiting for the doctor to make a call on whether we would proceed or not.

According to the fertilization report, we had 2 frozen embryos remaining in a straw together: a 5-cell BC grade and an 8-cell B grade (my clinic uses an A-D scheme to rate fragmentation, with A being the best). My RE had told me not to expect much from the 5BC, it was not such a good embryo and would be likely to not survive thawing.

Anyhow, the RE doing the transfers comes out and tells us that our embryos were initially a 9-cell BC grade and an 8-cell B grade and that after thawing, the 8B only had one surviving cell and wasn't viable (this was supposedly our good embryo) and that the 9BC had 7 surviving cells and was viable to transfer.

Objectively, none of this information added up at all to the original information we had about these embryos: a 5-cell BC and an 8-cell B were supposed to be in a straw together but it turns out that it was actually a 9BC and 8B and that now they are 7BC and 1B? It just didn't make very much sense and I guess that is why the lab was waiting for the RE to make the final call about whether to proceed with the transfer of the one remaining mystery embryo. I saw in marker on the updated report print-out where someone had crossed out "5 BC" and written "9 BC."

The RE told us that it's possible that the 5 BC just "grew a lot" (almost 2x?) in the time between the final grading report and being frozen. This explanation really doesn't make much sense biologically, and all of our other embryos remained the same in cell number, so it doesn't seem that a lot of time elapsed between the final grading and the freeze.

We went ahead and transferred the one remaining mystery embryo at the RE's urging but I am still so confused. In other news, I got a horrible migraine yesterday after the transfer and spent the night vomiting (sorry for the TMI). It seems like there are 3 possibilities here:

1) They got confused between the 5 BC and 8B in the same straw - it makes a lot more sense that the 5 BC wouldn't survive and only 1 cell would remain viable and that the 8B would remain viable but lose 1 cell, making it a 7-cell embryo. I think this is the most attractive and reassuring explanation, even though it's not the one they were offering us.

2) The 5BC miraculously almost doubled in cell number between the final grading and the freezing although during that same time period, every other embryo remained the same in cell number.

3) The 2 embryos in the straw didn't resemble the original embryos we froze because they weren't our embryos (this is the most horrifying explanation but also the most unlikely). I know this is probably almost impossible but the thought crossed both Y's mind and my mind independently.

Thank goodness we have our long-awaited appointment next week with the new RE. I am ready to run, not walk to a new clinic. I am curious, in this situation, what would you guys have done? Would you have still gone ahead with the transfer? I like to believe I would have at least asked to speak to the embryologist and the lab directly and see what they have to say, but in the pressure of the moment, when everyone was trying to work quickly and there were still several women waiting behind us, I guess it was hard to press for more info or reassurance.
