I was also surprised to see that he did not do mine!!! I had an array of doctors....one doctor I had never met did my ER, then a couple others I had not met did my ET...the way I saw it was this: It is a huge team process where I went at RSC. The nurses relay information to us from our FS who is overlooking our entire IVF cycle the whole time...when to trigger....when to stop estrogen, when we are ready for ET....so I kind of just got used to all the different doctors. At this point, I am not even sure my FS does ET and ER!!! I feel I could have researched a bit more-but I take it that my clinic is very experienced and that everyone there is the best of the best. I am thrilled with my results regardless-everyone was just so amazing to DH and I throughout the entire process. I believe before my scan I will have one last chat with my FS then I will have my scan, eeek!!
