the anxiety is awful when you have no idea what is going to happen, especially when you don't want the same issues to re-occur. I too have issues with follicles growing very quickly, and I don't understand why sometimes they do and sometimes they don't. i know this post is too late to offer any real advice for calling C.ooper today, but i was wondering if you explained to them your fears, if they would let you trigger earlier? Especially since last time the follicle got too big. I assume you are going in tomorrow (sounds like it) so hopefully it didn't grow too fast. but you'll see tomorrow, right?
One thing I believe MargieD suggested and which I thought about doing myself was just some "regular" non IVF cycles, just so they could see how things go. I learned a lot during my last IVF, and that is basically that my follicles must be triggered much larger than normal! and also that my new protocol didn't help recruit extra follicles. I think that they can get a good picture how your body reacts over time, which can be helpful during IVF. I know this is your last IVF, and of course you won't convert this to IUI so I don't know if this suggestion is practical at this point in time...but, if you ever reconsider IVF, it could be something to think about.
I really feel your anxiety, and I really hope things go your way and you trigger tomorrow.
I hope you post an update tomorrow so we can see how things went. i am nervous for you, I was just thinking that maybe you were getting ready soon for ER.
