"i have had the mirena for a little over 2 years. at first it was a real pain! it hurt so bad to have placed and i had a heavy period for almost 2 months straight. but then the bleeding stopped completely. overall, i really like having it. it has helped me have fewer migraines, it is so great to not have a period and love not having to worry about getting pregnant. however, i do have bloating, painful cramping every few weeks, and i&#039;ve just started having some back pain which i think may be connected. right now i can tolerate the side effects for the benefits it gives. i have thought about getting it taken out, but i really don&#039;t want to go back to horrible migraines or any other form of birth control."
