"i got mirena inserted when my son was 8 weeks old. he&#039;s now almost three. when i first got it, i thought it was great. my periods were lighter, and eventually i didn&#039;t get one at all. but about 4 months after i got mirena i start having sharps pains in my side and migraines every-single-day! not to mention spotting, and not knowing when my period was coming on. a few months ago i was researching mirena and all the website where women could write about their experiences with mirena, and we all had problems that were so much alike. so a month ago i got it removed. just like the post from other women said, i felt an instant sign of relief throughout my body. i haven&#039;t had a migraine since then.
