We'll be going to blastocyst if we get enough embryos. The way my clinic does things, if there are 3 or more on day 2, they go to blast, otherwise they transfer anyway. The idea being blasts have a greater chance of sticking (apparently), but it's better to transfer something rather than nothing if there isn't enough on day 2. I haven't got all of that aspect of things fully figured out just yet, but I'm working on it.
