If the lab is as good as you say it is, I'd ask the embryologist. And your dr. Something is up with your quality then. If lab is good. EIther they were all cromosonally not healthy or they have other quality issues. Cromosones you cannot change, but for example low carb diet for good quality is advised by dr Potter. I had lots of non healthy embryos to testing n day 5, my worse cycle was 8 out of 9 non healthy,... So should be other issues aswell.
