"i&#039;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&#039;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&#039;t feel it. just random small cramps but that&#039;s all."
