In May 20th I decided to get my cooper IUD. Since the beginning I had horrible side affects it's started off with heavy bleeding and painful cramps and back pain. A month later a lot of vomiting during my period. I was always nauseous. It continued to headache that's turned into migraines. Now it's everyone and more. Anxiety, skin dryness, and fatigue. I feel like I have no control of my body. The doctors are only giving me this to try to stop the symptoms but nothing seems to work. I need advice am I have a cooper allergy? Or can it be something else?

Please help
