M2C, remember that this is NOT your fault! I can understand that they were being cautious with your hyperstimulation history (I sometimes wish my clinic had been a little more cautious on my 2nd cycle with mine ), but all is not lost yet! Trust me, avoiding OHSS on an IVF cycle is something you REALLY want to do - I spent a week in hospital and a month off work... and it wasn't until my 3rd cycle that my clinic decided they needed to be extra-cautious and watch me very closely.

Good luck... and hopefully the next attempt won't be needed, but you know they'll have a better idea of how you respond even if it is.
