The Big Thaw...

Today we're thawing four embryos and so hoping for a good survival rate.  And so I consulted the Google oracle to find out more.  Apparently about 70% of embryos survive the process of thawing.  And interestingly not every cell of an embryo has to survive the thaw to be viable.  I also learned that whereas freezing takes 3-4 hours, thawing takes 45 minutes!  Somehow all this detail seems important to us.

Apparently the next stage is to 'culture' the viable embryos for a day or so before transfer.

More important, perhaps, is that we now know that a pregnancy test takes place 12 days after thawing rather than 12 days after transfer. So now after a couple of months of calm, this means we also know the exact date of our next pregnancy test.  So we're back to the now familiar territory of waiting and hoping for good news....
