"I've had the copper IUD for only 4 days and want to share my experience with insertion. I too made the mistake of believing the reviews about how horrible it was supposed to be. I was nervous and anticipated a lot of pain. But it really was not that bad. The pain felt like a strong cramp and lasted for about 3 seconds. It only hurt when the clinician measured my uterus, the insertion of the copper iud wasn't bad itself. She did it wrong the first try so she took it out and put a new one it. It was painless! However for a few minutes after I felt dizzy and nauseous. They let me lay there for a while and gave me Midol. Cramping and spotting lasted for 2 days now I don't feel it. Just random small cramps but that's all."
