"i have had mirena for going on 4 yr in june and love it!  insertion was quite uncomfortable... but not bad!  i never have suffered from bad cramps and continue the same (except 1 night having extreme discomfort.)  my boyfriend picked me up from the couch and took me to bed... i was in so much pain.... constant most horrific cramping... crying myself to sleep... he wanted to take me to hospital!  and i have had 2 kids 1 vag 1 c sec.  but i just wanted a dark rm and sleep... woke up the next day normal!  only bad experience the whole time!  periods have ceased at moment... but usually monthly until 2 months ago pretty normal until stopped!  but i do recommend and give 10... even with the 1 night!  implanon was bad... constant period!"
