Hi, Magi. I've never gotten so far as to have embryos yet, so that's a whole set of knowledge I just don't have...sorry. Hopefully the wise women of the board can step in and let you know what they know.
I honestly have no idea what grade my embies were (success)

I used donor embryos and I knew whether they were early blast, expanded etc but no more. They were the fourth transfer from the same set of embryos so certainly not "the pick of the litter" yet the three transferred produed twins. My best guess is the letter grades on this site are similar to what your doctor useshttp://www.advancedfertility.com/blastocystimages.htm

My clinic doesn't usually do blast transfers, but because I had 6 frozen at 2pn(pg)

and 2 at day 3, I asked them to thaw and try to take them to blast. The two I transferred were 5 day blasts, one was hatching and the just a blast. I asked them about quality and they just told me they were fair, whatever that means. It didn't sound good to me. The results, pg. with boy and girl twins.
My clinic uses letters to refer to amount of fragmentation. (preg and m/c ment)

A is less than 5%, B is 5-25%, C is 25-50% and D is greater than 50%. It may be different at your clinic and I think the grading is only a small piece of the puzzle. On a fresh transfer we transfer one grade A embryo with perfect symmetry and got a BFN. Did an FET of a grade B and got a BFP with an initial beta greater than 400. Unfortunately it ended with an early m/c. We have one more grade B that we will thaw and hopefully transfer the end of this month. After the grade A did not work I had no hope for my grade B frosties but I was pleasantly surprised and I'm now more hopeful about the upcoming FET. Good luck to you!
We transferred a single Grade B embryo and are now pregnant. We also did genetic testing on the embryos and none of the healthy embryos were graded A. Go figure! There isn't a strict corelation between grading and viability. Good luck!!
Just to let you know my clinic told me that Grade A embryos are rare, that means they are absolutely perfect. Grade B are really good embryos and Grade C is still good. I am part of the Resolve group in Dallas and just had a couple of girls in our group get pregnant with Grade C embryos. So it looks like you had really great results! Best of luck!
