It doesn't need saying that I'm disappointed. I'm also annoyed with the utter waste of time, but that's how this game works.
To answer some of your responses on getting a second opinion, there are a number of reasons why I want to inform my RE of this myself.
He'll probably be notified by the clinic staff when I request my records. I have to get my records before going to Bigger Clinic, because they want to see them at the appointment.
Also I want to keep my RE in the loop, because I hope he would be willing to do preparatory bloodwork and U/S even if I were to cycle with Bigger Clinic. Given that he already cooperates with several clinics, this is conceivable (no pun intended).
But first, I'm taking a small break. I may - gasp - even take a break from blog reading. We'll see.
