"mirena has been great! i&#039;m going on 5 years in february and have had a wonderful experience. no pain, no cramps, the only bleeding i&#039;ve had has been spotting and that happens maybe once a year. i am going this february to have my second inserted and from what i have read it appears it may be a painful experience. however, i am optimistic and hope it is as good of an experience as these past 5 years."
