We went to the clinic to pick up the kids today, hoping there'd be one or two left.
There were. We transferred 2 rather gorgeous Grade 1 blastocysts* and one spunky Grade 1 early blast.** One Grade 2 early blast and two Grade 2 morulas*** (they're a little slow -- about a day behind, but could still turn into blastocysts) are still in the dish. If they make some progress by tomorrow morning, they'll stick 'em in the freezer just in case.
Dr. Glass Half Full was absolutely incredulous. She said that the number of healthy blasts was way better than she would have expected from someone with an FSH of 13.7.
So now we wait. And wait. And hope, and pray that these little blasts (a) have healthy chromosomes and (b) find a nice soft nest in there, and stick, and grow.
Photos of our lovely blasts to follow, as soon as I'm allowed off the couch. I'd love to hear some ideas for how to distract myself until the pregnancy test.
Some definitions, for those of you who aren't embryologists or intimately familiar with IVF:
*Blastocysts usually develop five days after fertilization. They consist of 60-100 cells, and the cells have differentiated into two types: an inner cell mass, which will (we hope) become the fetus, and a trophectoderm, which develops into the placenta.
**An early blastocyst is an embryo that has reached the blastocyst stage, but is a little bit behind in terms of size and/or cell differentiation.
**A morula, so named because of its resemblance to a mulberry, is an embryo that hasn't reached the blastocyst stage. It consists of 12-32 cells packed tightly together. Embryos usually reach this stage four days after fertilization.
