"after having two children, i opted to have the mirena inserted at my 6week pp visit, instead of using the pill. the insertion wasn&#039;t painful for me personally, however, i had it put in mid-end april, and it is now 4.5 months later and i have had bleeding/spotting everyday since that time. i have yet to have an actual period, but have spotted / bled enough every day since the insertion, with more painful cramps (daily) that i had previously on a regular. cycle. also, i never experienced migraines in the past, and since the mirena i get them frequently (at least one biweekly) that brings nausea and effects my vision. i waited 5 months to give my body time to adjust, but at this point yes it&#039;s doing its job but the sideeffects are not worth it"
