Thanks everyone. Some days I'm simply astounded by the amount of stuff that you learn going through assisted conception. Although, I'm glad I never became a doctor! It's hard enough to get my head around the things that I need to deal with - I don't think I've got the brain capacity for what a doctor needs to know!

And I'm awfully relieved that I wasn't the only one to have that reaction to the term "collapsed blastocysts"! It sounds dreadful, but it's actually a good thing!
