Iud pain

I’ve had the iud for one year now and for the past few weeks I’ve been having pain in my lower abdomen. It started out as very mild cramps but over the last two weeks it’s gotten worse and worse and now I’m in so much pain. I can’t eat, I can’t sleep and I have a one year old I’m having a hard time caring for. I can now feel the IUD moving around and I have been having some bleeding. Not super heavy but more than I have had all year of having it placed. The earliest I can get into my doctor is the 24th and probably going to have this stupid thing removed. I’ve also had these very hard tissue like things come out and I have no idea what they are. I am not pregnant! I’ve taken several tests over the month just to make sure I wasn’t. Not even the tiniest faintest if lines in any of them. Any one else have this kind of pain and issue with the iud? (liletta) picture below is the only good photo of what keeps coming out
