I'm so sorry :( I failed my first IVF in September so I know how you're feeling. I didn't go in with a ton of specific questions for my appointment except - WTF happened? I guess the questions I may have asked, or at least things that came up, were:
Based on the cycle, did he think my eggs/embryos were good enough quality to try again or did he think we should move to donor eggs. I'm 41 so there is definitely a worry of my eggs just being too old.
What he thought we should do differently, if anything, next time.
If you didn't have an endometrial biopsy prior to your first IVF, you may want to ask about that. It's a pretty painful procedure but there is a bunch of research suggesting that it may help with implantation. (You may want to google "endometrial biopsy and IVF" to get more information.)
If you weren't on them before, I would ask about taking DHEA and/or CoQ10 to assist with egg quality.
That's all I can think of right now. Take care of yourself!! ((((hugs))))
