"i have been on the mirena for a little over 2 years. i experienced a lot of irregular bleeding for the first few months but by 6 months i no longer had any bleeding at all. i have been almost 2 years without needing tampons and i love it! i love the mirena because there isn&#039;t any mess; i don&#039;t have to remember to take a pill or put on a patch, and i love how effective it is. it is also much cheaper in the long run. now for the side effect. i have become increasingly aware that i have extreme mood swings more frequently. i just thought that i was depressed by life events but lately it has been more of a roller coaster of manic mood swings. after some research i found this to be a common side effect. i am currently seeking ways to offset this"
