What was crappy about them? their grade or how they survived the thaw? my day 6 blast is a 4BB, but it was thawed to biopsy it, to test if it was genetically normal, and when they thawed it, they told me 80% cells survived the thaw and then it was refrozen. so it's a pretty good grade (4BB is a nice grade, I think) but it seems to have lost some cells on thawing, so even if it thaws perfectly a second time, ... but it was CGH normal upon testing.

This was exactly me as as well, except I am due with my crappy looking day 6 blast in a month.

my "perfect looking" Day 5 blast never implanted. my Day 6 "crappy" blast will turn one year old next week. you just never know on this journey. good luck.

Your blasts from day six were not blasts yet on day five you mean?

Both my kids are day 6 blasts. Day 5 didn't take.

I don't know that there's a "rule" that will be helpful OP. Everyone's experience is so individual.

I will tell you that for me the only ones that worked were my day 6 blasts, and they were graded lower than others we implanted.

Go figure.

Good luck!

Do you go with which one has the better grade or is day five preferable
