Caesardust - on my first cycle I prepared for an fet the next cycle in the hope I would get a PGD normal embryo. There was no cost but maybe that was because I didnt take any meds and only had a trigger shot . That could be the reason my FS said I could prepare for a transfer the next month. Might be a different story of it was a medicated fet. I did this on my second PGD cycle as well and on the third decided not too as I found the disappointment harder to deal with when I had nothing to transfer. I think preparing for an fet gets your hopes up even though you try and tell yourself it doesn't.
