Wishing4.... what a lovely story about the donor embryos you've been offered. I'm sure you'll work out the timings so they're right for you.
AFM.... scientist rang this morning - embryo is still battling, but is only at 4 cells, when on day 3 it should really be 6-8 cells. They're not going to take it out of the incubator to look at it tomorrow, so will next look at it and ring on Saturday morning before we leave for the transfer. I'm not too worried, as I've read things about "slow" embryos catching up or turning into beautiful babies, so I'm just rather pleased that it has continued growing. If I don't get to transfer, then I'm fairly at peace knowing that it would have been unlikely to have kept growing in my body. At the moment, just glad it's got this far :-)
