It's probably too early to think about, but I'll just throw this out there.
If your problem is with egg quality/quantity, then the skills of the lab where the embryos are cared for is crucial. That was my problem. That's why we switched out of state to the Colorado Center for Reproductive Medicine (CCRM) in Englewood, CO. (They're actually in Lone Tree, CO, now.) When you don't have a lot of good eggs to work with it's so important that the clinic where you go has a top-notch lab.
Forgive me if you're already aware of this, but I'll give you a link to the CDC stats for labs across the country. I see your lab in there. Take a look at CCRM in CO. They are almost double the national average:
Like I said before, for me it always gave me comfort to have the next step planned in case things didn't go well. And, just in case you don't get the results you want I thought it might be good for you to know that there are other options. If thinking about this stuff is stressful right now please just ignore my ramblings
I'm not sure how similar your wife's situation is to mine but here's my story (I posted about a month back on a diminished ovarian reserve success story message board): http://www3.fertilethoughts.com/forums/ ... ge=1&pp=10
My story is the 5th post down on page 1, post #148. I know when I was struggling that it always helped me to hear about people in similar situations who had success.
All this said, I am hopeful for you! Please know that all of the above is "just in case". Good luck on the 13th! Try not to worry! There are still lots of options and a good chance that you will get the news you want on the 13th!
