"i am 23, and i have had mirena for the past 5 yrs. it was placed in a month after my son was born and i now have gotten it removed and a new one inserted! i loved it the first time i occasionally spotted but rarely more than 1 day. the reinsertion was a different discomfort then what i experienced the 1st time. i have had a lot of cramping, even in my legs. hopefully it doesn&#039;t last."
