Hi... just wondering... do you have PCOS at all? It can lead to a really unpredictable response to puregon and other stim drugs.

Unfortunately, there's no real way to know how likely you are to overstim until you get there. I had OHSS with all three of my cycles - the first two were so bad I was unable to have a transfer and with one of them I spent a week in hospital with it. I know how scary it is.
