the temp is actually a pretty big deal. The high I would have worried about more than the lows actually. As long as you are still showing a decent embryo attachment spot though it is probally ok. The temperature should not fluxuate too much during the first 2 weeks of embryo development. The first day or so I don't think it matters a whole lot as far as cool temps but highs over 95 probally are not too good. I hope it stays ok for you.
:is the temp. a big deal? of what happened? i talked to a friend of mine thats a breeder and he said that they are dead most likely but it has red in it still but isnt plump. :
