"i have had the mirena placed 16 months ago.  i am 30 and have 3 year old twins. it was a little bit painful to have it placed.  the mirena has helped my mood swings and not so much for the acne.  i was iffy about if the first 5 months i had it.  i cramped hard and the bleeding was heavy. i have always been a spotter not a bleeder.  but after 6 months, it lightened up and now i only have light spotting.  i don&#039;t miss taking the pill everyday.  my moods are wonderful!  i used to be an emotional roller coaster with other birth controls.  i am retaining my baby weight.  i can not shed it.  i exercise,  i don&#039;t know if it is just me or if it is the mirena holding onto what i have.  i don&#039;t plan on having it taken out any time soon."
