IUI on hold

I finally made the decision to go forward with IUI. I felt good about the decision. It was a small step, but one in the right direction. I called the doctor and made an appointment for our consult visit on August 27th. In the meantime, I figured I would try to get a diagnosis for the pain I've been having in my bladder since my c/p last July. It is sort of a stabbing pain, or a heaviness in my pelvic floor and it is so bad when I have my period, that I cry (but only when I pee!).
So I saw my gyno today and after listening to my symptoms, she suspects it may be bladder endometriosis. There is no cure for it, it is only treated with pain management. In order to diagnose it, I have to go back on birth control pills. Maybe for 1 month, maybe 2, maybe 3. Just to see if my symptoms go away when I get my period, on the pill. If they do, then she can diagnose it as endo. But even so, there will be nothing I can do about it, except stay on the pill to manage the pain. Which obviously I can't do if I am trying to get KU! It is so frustrating. Why did I wait to go see the doctor?...I should have gone months ago.
Why do I feel like there is some greater force trying to do everything to prevent me from getting pregnant? This is all beyond frustrating.
