Thanks everyone.

I would be quite happy to get to epu and not transfer. Well, not thrilled, but at least feel it wasn't all for nothing sort of. I just have to hope that not all the 40 that are there today, keep growing. I am drinking 2+litres of water and powerade, but so far, I don't actually feel sick or anything, just a bit tired and slightly tender ovaries. I was not expecting this at all, and so am a bit shocked too I think. I have always taken weeks to stim (eg in IUI).

I completely agree with what you have said, and if we DO end up cancelled and tack on yet another few months delay, then so be it I guess. Its not the end of the world, I'd rather than than be as sick as you have described (sounds dreadful you poor thing). I am trying to be rational and practical, though I am sure I will be disappointed in the event of it all ending here. I just have to see what Friday brings, but I don't feel too hopeful. Thanks for such a detailed and helpful reply BW.
