@emilyjohnson25 welcome to Mayo Clinic Connect. What is “(16F)”? Just making sure I’m on the right track. I’m sorry about your bladder/abdominal pain. I’m not sure that an inter uterine device (IUD) would be associated with your your bladder/abdominal pain but it would certainly be worth ruling out as a cause. My daughter had an IUD that morphed out of position and caused some sort of uterus problem. It was discovered and corrected in an exploratory surgery. It is a good idea to seek treatment. Perhaps you can start with the provider who placed the IUD?
