Of course there are pros and cons with every decision in this process, and there are very good reasons for going to day 5, but I was interested to read this, as I had always wondered why they did them at day 2 when everyone else seemed to have at least day 3s......

my FS this morning was saying one of mine would not freeze, but that was still okay for transfer, so... if we had have left it it might not develop further, but tucked nice and cosy inside me, it might implant.....

anyway..... I guess that's what makes some of this all about luck, you just never know whats going to work and what won't....
