"i&#039;m almost 16. i had mirena inserted on may 25th, and so far i have loved it. i occasionally get crampy and my stomach hurts, but not often. the insertion was pretty painful (i can tolerate pain very well) and i just took some ibuprofen afterward. i have bled lightly for most of the duration i&#039;ve had the mirena. i haven&#039;t had any strange side effects. i was on the nuvaring before and it made me dizzy. that&#039;s the main reason i got mirena. my acne hasn&#039;t changed, gotten worse or totally cleared up. i like my mirena so far.
