Yes, I did work up the nerve yesterday to call and ask. I was right, which completely FREAKED ME OUT until the dr. called me and explained that it wasn't MY embryo in the picture. His new HP printer apparently has a mind of its own and when he clicked on my picture from the slide show and it gave him a different one. He said it happened again when he tried to print a day 3 and got a blast... so I understand what he is saying and it is the BEST CASE SCENARIO of course. He assured me MY embryos are in ME. :) - Like the 2WW isn't stressful enough!!!
From what I understand when ICSI is done, they hatch the egg with the sperm so it's a pre-embryo, or a blastocyst as it splits & divides. They hatch on the day of the retrieval & 3 or 5 days later they transfer the embryo. So the sperm shouldn't be hanging around the edges, especially that many. They take the "best" sperm & use it to fertilize the egg. I would ask the clinic. You have every right to ask them, even if you think they'll think it's silly. Let me know!
