Yeah Leabie, I think freezing a few just in case is a good idea. For the cycle we got DS we put 4 in the freezer at day 3 and ended up with 3 blasties.
This time the embryologist recommended thawing the 4 day-3s and seeing if we could get any blasties - only one made it. So we still have our 2 'backups'

It's interesting (in a way) and I'm not sure why, but some people seem to do much better with blasties and some with day-3 embies. Blasts seem to work better for us.

Albi - I guess it can be helpful at any stage, but I know it's often recommended before and after transfer.

Hi everyone else - Hope you're all travelling well. I'm mostly just back to lurking these days
