Hi Babymama,
I've never heard of a nasal spray trigger so maybe it's something you dreamed under sedation there again it could be totally real!
Are the clinic updating you each day to how your embryos are doing or do you just have to wait till friday?
I think a FET is much better option given that huge egg haul I'd imagine you won't be feeling so great over the next few days. I was never surprised when I didn't fall pg on a fresh transfer as I always felt so ill after my collection.
Looks like there will be several of us doing transfers in Jan and Feb
