Only 1 embryo biopsied?

MJ

So I had 12 eggs fertilized on 4/24 and this past Sunday was Day 5. I was just told that only 1 embryo was biopsied today and now I'm waiting to hear from the RE to see what is going on with the other 11 embryos. Is it possibly that the the embryo can go to day 7 to be biopsied or even be viable? Does it sound like I'm going to loose all 11 embryos?
