"i&#039;ve had the mirena for about 5 months now and i&#039;m still not sold on it.  the pain during insertion was high and i had horrible cramping for the next few days.  my periods are about a week and a half long, granted it is light and is more like spotting but it&#039;s real inconvenient.  i still get pretty bad cramps accompanied with it too.  you&#039;re told to give it about 6 months to let your body adjust to it so i&#039;m hoping it gets better."
