"i had the mirena put in 3 years ago. the insertion was extremely painful (i haven&#039;t had kids) and i had bad cramps for 2-3 days after. after getting over that first hump, i didn&#039;t get my period again for 3 years which was awesome! however, it did cause me to develop cystic acne which i didn&#039;t have before so consider this possibility before having it put in. if you aren&#039;t acne-prone it&#039;s an awesome form of bc!"
