Well the bad news is that 2 out of the 4 embryos weren't good. They were 3 and 4 cells, and fragmented. So they were disposed of. The good news is that the 3rd embryo is 7 cells and not much fragmenting. It was good enough to be frozen, so it's now on ice. The 4th embryo was a perfect looking 8 cell, with little to no fragmenting. It's what Boston IVF grades as a HIP (high implantation potential)embryo. My RE strongly recommended only transferring 1 since it's such good quality. It's not that I want twins, but I hope that it was the right decision to only transfer 1 back.

So now I just wait again..............
