Kell, I've been in a similar situation. My first stim cycle, we got to EPU, but didn't get to transfer. I woke up with the magic words "freeze all" on my hand along with the number 26. For us, they started to get worried at my first scan. At the second scan, I was told I had enough dominant follicles to go to EPU, but if I'd stayed with lots and lots of small ones, it wouldn't have been worth collecting. They will do their best to get those eggs collected, but remember if they are talking cancelling it's because they don't feel they'll get any eggs worth using. If you get to EPU and they suggest freezing all, don't fight it. I was sick for three weeks with my case of OHSS, I've never been so scared or felt so unwell in my entire life! OHSS gets worse if pregnant, I only stayed out of hospital through stubbornness and sheer bloody-mindedness (I refused to go because I couldn't fit into any clothing, and wasn't going to go in my pjs in case I saw a student there), if we'd transferred and it was successful, I'm told I would have most likely enjoyed a long stay in ICU fighting for my life. It is scary! Rest, keep hydrated, follow your clinic's instructions. As disappointing as it would be to cancel, or collect and then freeze, remember that it's all in the interest of keeping you safe and well. I'm still at work, but I'll be home shortly (after medicare), feel free to PM me to ask more.
