"my expirience with mirena has been ok so far. it is nice not worrying about getting pregnant but after getting it put in at my 6 week post pardom appointment i had a lot of cramping and spotting for about a month. since then i still have a period and it is abnormally heavy and miserable. before mirena i had light periods without any symptoms at all so this has taken some getting used to. i would still recommend it because it is nice to know you are protected and you don&#039;t really have to do much to keep up with it."
