I might be guilty of doing the Carlton dance in my living room about five minutes ago. The embryologist called and our last little embryo made it through the night and is a 6BA. Now it is just the waiting game on receiving the chromosome testing results. For my age, there is a 62% chance of the embryo being normal. If it does come back abnormal, it will come with a report letting us know what was wrong — i.e. Down’s Syndrome, Trisomy 13, etc. Any abnormal embryo will be ineligible for transfer and either destroyed or else we’ve agreed to let testing/research be completed on the embryo.
If you aren’t familiar with the grading of embryos, there is a very helpful explanation here. The grade of an embryo doesn’t equal success — there are 3CCs that go on to become healthy kiddos and 6AAs that turn into negative pregnancy tests. It really is just the luck of the draw.
