I got a call from the RE himself on Wednesday with the results of DH's genetic testing. DH is a carrier for exactly one thing. To quote Love Actually, you may have guessed it, but you may not believe it, it's SMA!
So now we get to learn a lot about pre-implantation genetic diagnosis. The article I just linked to provided some really good information. We still have a bunch of questions for the RE when we meet with him next Friday, though. One question that I have for anyone who has needed PGD is how significantly it impacted the number of embryos they still had to transfer/freeze, whether they still had enough.
The biggest impact that the news has on me is that I finally have some sort of answer to the cosmic question of WHY. Why we had to deal with infertility. Why we couldn't have our first cycle when we were supposed to. Why we weren't able to do what so many other people can do so easily. The question of why is still on the list of questions I have for God when I get a chance to ask him, but it's moved a lot farther down the list.
