"got it when i was 18. no kids. covered 100% insertion felt like a bad period cramp. was over before i knew it. cramped for maybe a day or two. manageable. my partner hardly complained that he felt the strings they never hurt him just sometimes they needed to be adjusted. i kept it in for 6 years because i didn&#039;t have insurance anymore. on the 6th year i had a light regular period. i had no weight gain, no mood swings (hormones are localized with mirena), no acne problems. no side effects at all."
