"i have had the mirena now for 3 years.  the insertion was painful but after an hour i felt fine other than mild cramping. i spotted a day or so after insertion. i ended up only having 4 light periods after that each month and then haven&#039;t had a period ever since.  however, the bloating and headaches still come at the same time every month.  it is great to not have a period. mine used to be very heavy that always lasted the 7 days.  i have noticed recently though that my back pain is something that doesn&#039;t seem to go away after the false cycle ends. other than this, my experience has been great."
