"i&#039;m 19 and recently had the mirena removed. i had it inserted after i had my son when i was 16. i really think it&#039;s a great birth control, it&#039;s a fool proof way to not get pregnant again (which at my age i obviously need). i don&#039;t have any complaints when it comes to weight gain, my skin actually got clearer and for the most part had painless, lighter periods. the only reason i rate it a 7 is that i did have several ovarian cysts that weren&#039;t dangerous but i&#039;d consider definitely annoying. another thing: i think it better suits married woman because the risk of any infections that cause pelvic inflammatory disease is obviously less with one partner."
