"i have had a mirena for a little over a month now. i was very scared about it after reading negative stories online.  however, my experience with mirena has been mostly positive.  this past month i have had off and on light bleeding, my actual period lasted a couple days and was way lighter than i am used to.  my acne has improved a great deal (which is a huge positive).  my partner can&#039;t feel the strings. i did experience some occasional cramps, especially the first couple days after insertion (for your information insertion pain was minimal).  so glad it&#039;s working out because i paid hundreds of dollars out of pocket, since my insurance didn&#039;t cover it."
