"i have had the mirena for almost three years now and love it. insertion was not painful at all. just a little uncomfortable. i bled for two months then my periods went back to normal. after a year they went away completely. i&#039;m very thankful for that. i suffered from really bad menstrual cramps and severe mood swings. once i got the mirena my moods seemed to balance out. my cramps have disappeared. i have noticed even though i don&#039;t get a period i still get minor pms symptoms. i would recommend this to any woman looking for a convenient birth control that works. also i am glad it does not have estrogen in it. some of the estrogen based birth control gives me migraines and causes me to be moody."
