Farmgirl - so interesting - I am with Julie Whitehead and just asked her yesterday about going to blasts. I've done a bit of research and given my age I think this is the best way to go. She did say that she would do so, but only if I got more than 3 fertilized embryos as if there are less, then she wouldn't want risk losing them all before transfer as I do think it's a bit harder for them to survive our of your body (but then again, if they wouldn't survive anyway, it probably doesn't matter). I think it's all a bit of a gamble, but I am a firm believer of doing your research and deciding what approach you are most comfortable with - with the proper amount of deference to the experts (i.e., your FS).

I also bugged her about the what if's - my DH laughed - but that's my way, I wanted to know what approach would be next if this cycle didn't work (I have my egg retrieval on Monday). If this cycle doesn't work, then I'm going to 1 - continue to push for blasts where possible and 2 - push for 3 embryos to be put back in. I know I harp on this, but I have 3 over 40 friends back in NY who all had happy & healthy single bubs via IVF (with their own eggs) all of whom used blasts and had 4 put back in.
