Just as a tale of caution, I had a Mirena placed in 2011 when I had early onset menopause and my periods became very heavy (almost needed iron infusions) and painful. It did change my periods; they were several weeks per month but at least not heavy or painful. However from the time it was placed, almost to the day, I was a psychiatric mess. I was suicidal, in the hospital twice in a few months, and my moods were completely out of control. Finally after 9 months we decided to pull it to see if it was the problem. My GYN said it shouldn't be the cause but that there was no way to know. It came out and within a few days I was much, much better. I had a hysterectomy a few months later and now am all done with menopause at 40. I seem to have less extreme rapid cycling now although I still have plenty. But it is different.

My pdoc and GYN talked about the Mirena issue for me and within a few week both found other women who were affected the same way. Because of me Mirenas are used with much more caution in mentally ill women at my hospital.
