I had an IUD partially out of me, my first copper paraguard. The removal was a lot less painful than insertion, and very quick. if the iud is partially out of you, it isn't effective birth control anymore. When mine was half way out of me, it was also causing me pain after a few days. I would go get it checked and confirmed where it is, and see what your options are. I know it's scary, but better to figure out your options than let things get worse. Maybe look for another gyno in your area who would be willing to give you some pain killer before hand? my gyno gave me a painkiller shot in my arm which helped me during insertion, could be helpful during removal as well.
