Hi to the newbies!
Rarah its a tough one as to whether doing PGD first is a better idea or not as I think you're only 35 right? Most of us here are over 40 and using donor eggs due to age related egg quality (aside from a couple of us). I think you have to ask yourself if you have it in you financially and mentally to continue with OE... You don't have the time constraints like say...me lol at 43.
I still had an OE embie when I went to cpt, but I just wanted the best odds of having a baby so I chose not to use it. Its really a personal decision x
