Thanks for sharing your story. I've been doing some research on Mirena and had no idea that it might play a role in autoimmune diseases. You should definitely share these concerns with your doctors, if you haven't already. The only risks I've read about include migration, where the IUD actually moves (and sometimes gets lots) causing infection, scarring, etc. It also apparently increases the risk of ectopic pregnancy. http://www.publichealthwatchdog.com/mirena-iud-has-risk-of-device-migration-m...
