"i had the mirena inserted two weeks ago on the second day of my period.  i have had two children and i didn&#039;t feel the insertion of the device at all.  my doctor did use the ultrasound machine to make sure the placement was correct.  i took 800mg of ibuprofen before i went to my appt.  i had slight cramping and have had light/bleeding since.  i am and avid runner and i have no problems with pain after rigorous exercise or intercourse.  i am hoping that as the weeks go by the light bleeding decreases.  it&#039;s worth 4 years of birth control to me."
