Don't feel bad Luv ok??? Everyone cops their fair share of sh!t (and more than their fair share sadly ) on this b*tch of a ride so there'll be no "fertilisation guilt" or any other guilt for that matter ok??
That's a great result Luv!!!
Yeah....it's always the going from Day 4 to Day 5 that you have the biggest drop off usually. That's par for the course unfortunately If you end up with half of what you started with by the time you get to Day 5 then you can consider that a bloody excellent outcome I reckon!!
The attrition rate is 50% I think for embryo's making it to Blastocyst stage???
