"i got the mirena 3 days ago and i&#039;ve had nothing but pain ever since. it&#039;s not severe pain, but bad cramps that don&#039;t go away, even with advil. the insertion was super painful and seemed to take forever, but that could have been because i had to get it done at a &quot;teaching&quot; clinic and the guy didn&#039;t know what he was doing. i&#039;m 28, no kids. i like the idea of an iud but i just don&#039;t know if it&#039;s for me."
