You have so much to think about now I know, but before you pull the pin I have one more suggestion for you to ponder on. Have you considered donor embryos at all? The reason I put that forward is that we have that as our fall-back option should our donor cycle not yield any usable embryos.
Donor embies are not as uncommon as you may think - they come up from time to time through EDA and Bub Hub - and the costs are significantly lower. Obviously you might have to go through counselling and FET costs, maybe cover storage and shipping costs if you wanted to move them from one clinic to another, but it's just something to think about. Plenty of time for that though, for now take care of you
