"i am a first time user of the mirena, i have to say it&#039;s pretty good. the inserting wasn&#039;t painful at all to me my dr was very gentle and walked me through each step it was over before i knew it, although i must say every since ive had it my period is very tricky. it seems to never go away. i have slight cramping but light periods and sometimes heavy. hopefully it will ease up and disappear soon. other than that it fits me best:)"
