Funmamma,
I did my first pick up with 60+ follicles no OHSS then another at 40 something no OHSS lol then one with 12 and got OHSS. I had 3 day transfers with the first 2 stim cycles but defered on the latest. I have PCOS and was only on 125iu. When I had OHSS I couldnt breathe but never needed hospitalisation. They keep a good eye on you when they do big pick ups , I think there are bigger probs if you go to transfer and falling pregnant with it.
I hope all goes well on Thursday
Bec
