Yep, definitely after the trigger, I'm afraid. If you think your ovaries hurt now...

I don't know whether it's the same for everyone, but for me I'd become very uncomfortable after trigger so that even walking hurt like hell because it would jiggle my ovaries around. There'd be a brief reprieve after EPU, the day following EPU I'd start to wonder what all the fuss was about, and why are we not transferring, I feel great?... And then, 2-3 days after EPU the worst of it sets in.

I don't want to scare you, but I guess it's better to be honest and upfront about what you are dealing with here. Rest is extremely important. Keeping your fluids up is absolutely vital - get gatorade and start guzzling! Especially after EPU, 2-3L of gatorade per day, absolute minimum. Buy the powder and mix it yourself - you get thoroughly sick of the taste after a while, but you need to do this. Don't do what I did the first time and think that you're ok, and you can go for a half hour walk on the second day after EPU... A high protein diet can also help, and rumour has it that sustagen is another good thing to drink.

Again, having learned the hard way - if you are in too much pain, or so bloated you can't walk, hospital is a damn good place to be! Check with your clinic on which one you should go to, as you need to be able to trust that the doctors there will know how to treat OHSS. The night I was admitted to hospital I freaked out a registrar who decided they'd do an abominal scan to see if they could see anything at all, but expecting to be able to find nothing until they could get me near an internal ultrasound probe... she found my enormously swollen ovaries sitting on top of my uterus, touching each other. It was all she could see. The following day when they took me for a proper scan after I was admitted, they measured my ovaries as something like 10cmx8xmx7cm. Grossly enlarged... painful, really not fun. The professor who did the scan explained (there was a med student in the room at the time) that if they didn't know my history, and just saw the scan pictures, they'd assume advanced ovarian cancer and be operating to remove my ovaries immediately. That's why it's important to get the right hospital and explain your condition carefully if you have to go.

That said, I know of other women who have been unable to transfer due to OHSS and have felt completely fine the whole way through.
