Just out of curiosity BW did your FS discussing freezing your embryos earlier due to the OHSS, last cycle when we couldn't go to transfer due to the OHSS. My FS decided to freeze the day after EPU, she explained that if this is done after ferilisation but before they start to divide you get a 100% thaw rate and you can grow to bast and then refreeze any excess. Apparently its the same as doing a fresh cycle because there is no cell damage. We will have to see if this is true when we do this But just though i'd share. But generally we got a 60% successful thaw rate on our blasts previously.

Hope yours behave and thaw nicely
