And today is the day!! We have 4 embryos that have made it to the mature blastocyst stage! Normally the embryos are assess on day 5 and then again on day 6. Yesterday we had 2 that were mature and 8 more that they wanted to watch for one more day. Today we have 2 more that are ready to go so we will have a total of 4! They are each graded BB if you remember the grading scale from my prior post. The guy at our IVF class told us "BB means baby all day long" So that's good. They have a very strict grading system at this clinic and 80-85% of the embryos they transfer are BB. They do not transfer CC embryos. Now they have collected a small sample from each embryo and sent it to the lab for DNA testing to make sure they have all of their chromosomes etc. The embryos themselves will be frozen until we are ready for a transfer in July! This DNA screening process will take about 2 weeks. Everything is looking good so far. I was a little worried yesterday when there were only 2 but 4 makes me feel a lot better as there is still a chance that some may have chromosomal abnormalities and not be able to be used. Or maybe they will all normal and ill have to talk George into having 4 babies. HAHAHAHA
