The clinic just called and we have 5 frozen blastocysts! Wohooo!!! 3 of them were frozen yesterday on day 5 and 2 more today on day 6! All of them are "beautiful expanded blasts" as my lovely embryologist said after having wished me happy birthday... Only 2 had arrested on day 3 but the other 4 didn't look high grade enough for freezing (my clinic has very strict criteria for what can be frozen, they like to have their FET stats almost as good as the fresh).
So that's it for now, we'll be looking at single transfers in the summer of next year (we have the California holiday planned for June next year and then I have a conference near Boston early July), I really hope there will be a brother or sister for Oliver among my little penguins.
