Birth Control
"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."
