"after having my second child, i developed a few ovarian cysts and endometriosis.  my doctor told me i needed birth control.  out of all the options with birth control, the mirena seemed to be the best option for me.  i don&#039;t have to remember to take a pill everyday, my periods are light to non-existent, and i&#039;m still baby-free and cyst-free!  this is my 5th year using mirena.  i just recently had it replaced (9 days ago).  i&#039;m experiencing a few cramps on my left side, and i was spotting this morning, but that&#039;s all normal.  the removal of the last mirena was a bit uncomfortable, but that&#039;s the only negative thing i have to say about it."
