So sorry for your outcome... your experience is so insightful as I would have thought exactly as you did after blasts that passed pgs.
Would you mind to provide more details? How many eggs your donor produced? Just two passed pgs? Any frozen embryos ? As you did pgs i assume you didn't syncronize your uterus with your donor. Did you transfer with a natural cycle or you preparred your endometrium before transfer? What would you change next time except transfer possibly two embryos ? Last question: how much did you pay? Any garanteed egg donation Program in NGC ? Sorry for all these questions but it seems your criteria of Clinic selection is exactly like mine ( adult photos, extensive donor infos , even donor genetic screening, pgs, (girl preference, however I would be very happy with girl twins)...
