"i am 29 and just had my second mirena inserted a few days ago. it was painful, but the pain only lasts for around 30 seconds if it goes smoothly.  i have seizures, and have chosen mirena because it does not interact with my medicines. other forms of birth control have caused more seizures. i do not have this problem with mirena. it has not affected my skin (although i currently use medication for acne i&#039;ve had for years).  i like it because after it&#039;s inserted, i can forget about it for a few years.  the only thing i&#039;ve found inconvenient, is having a partner be able to feel the strings.  but my gyno said most men are not even aware.
