@SJ89 - oh hun i'm so sorry to hear that ET got cancelled . The waiting really sux....we seem to constantly be waiting and waiting. But you are definitely moving ahead and getting closer and closer to that BFP. Everything crossed for you for Friday and you get at least 6 eggies and maybe even more! I know it doesn't sound like much but it really is quality over quantity and it only takes one .
It sounds like you have a good team behind you and changing that trigger shot is good so that you don't get OHSS. I hear of a lot of ladies deferring transfer, letting their hormones get back to normal and bodies recover, do a FET and get that BFP! In fact on the Monash IVF website the FET success rate seems to be higher than the normal ET. Some say it's to do with having normal hormone levels (eg estrogen).
All the best for Friday hun and make sure you keep up the gatorade and protein in-take! Keep staying positive. I just know you are going to get that BFP!!!
