Frozen embryo transfer

I was just told that I can no longer have a fresh embryo transfer this month because I'm showing signs of ohss. I'm only on day 10 of this IVF cycle and I stopped stimming last night but my estrogen doubled overnight to 5,000. My RE is looking to do egg retrieval on Thursday ( today is Monday) but is going to trigger me with Lupron instead of ovidrel. Has anyone else had this happen? Who knows what's involved in a frozen transfer? It hadn't occurred to me that this could happen so I didn't even ask questions about a frozen transfer.
