If I did decide to thaw say 3 x 3 day emboss - with a view to culturing to day 5 blasts - ideally to transfer 1 day 5 and refreeze the other two... I'd none of the 3 made it to day 5 - would they transfer one where it was at - or would all 3 be lost?
Def speak to the embryologist at your clinic - if a embryo doesn't survive the thaw, the definition of this would be determined by your clinic (eg what % of the embryo survived). Basically, if none survived to a decent %, say 70%, a good clinic won't transfer- you would have very low chances of success but would be charged for the transfer and hospital time which would be the full cost of the FET.
Given you have a few embies, all likely at different qualities, you should speak to the embryologist about the best approach to take. You want to take as many to blast as you can ( it's expensive to do it then freeze, then do it again later to other day 3 embryos) - my question is also why didn't they take them to blast seeing that you had so many? Normally they only do day 3's these days if they only have a few because you do lose more going to blast so they want to try and make sure you have something to transfer. I have a day 3 IVF bub and a day 5 - it's sadly not as simple as saying which one to transfer as there are a few complexities to it. If you call your clinic, a decent embryologist can help you with a plan of attack for your unique circumstance, I had quite a few different stage embies so they helped me work out the best way to do it.
I am going to call the embryologist tomorrow. To be honest your question is the one that keeps me awake at night!
Why with 10 embryos did they freeze them all at Day 3? I know I have 8 very good quality and 2 not bad quality. If I had have known more, then, I would have probably asked to freeze some at day 3 and take the other half to day 5 blasto freezing.
Anyway your advice is great - I wasn't sure if I was even able to call the embryologist now they are frozen, but ican scared about not being consulted on what comes next..... My FS is brilliant! But they don't have much time...
