"i had the mirena put in 2 years ago. there are only 2 things i like about it.  one, it stays in for 5 years (unless you decide otherwise) and two, i don&#039;t bleed as heavy as i used to. other than that i don&#039;t like it. i have severe cramping, horrible migraines the week before i start and the 5 days i&#039;m on my cycle, i also have extremely crazy mood swings. i am thrilled to have it removed in a few weeks."
