Kind of explains why you're not getting pg though if they're all duds? Even if mine are all wonky, that will give me closure on my 'own egg' journey. One door closes, another door opens and all that jazz. Really feel for u, that's hard news to deal with. There could still be a good egg in the tree though and the 'unknown' could be it. Really sorry this happened. Surely some of the pgd cost is offset by the lost time, money and potential emotional dramas you saved by not transferring the trisomys?
