Hi L.,
I know that Mirena has worked for many women, so I am in no way trying to change your mind. I wanted to share my experience so that you can be aware of the side effect I encountered because the medical profession insisted it could not be Mirena.
The convenience of Mirena was great. I spotted for three months and then my periods ceased. After about two years, I started feeling "not quite myself". I lacked the energy to do anything. I felt tingly and on edge, kind of like I was going to jump out of my skin. My family was at a loss and I was at a loss. At the time, everything in my life was running smoothly. I figured maybe I was going into early menopause.
When I approached my doctor she said that there was no way it was Mirena or Menopause. She suggested that I may be depressed which was did not feel right to me. She prescribed me a anti-depressant which I took. This medication intensified all of my symptoms. I immediately stopped taking them and called her. Again she insisted that the Mirena was not the problem and prescribed a different pill.
At this point, I made a decision that I knew myself well enough and that if I was truly depressed I would find a different way to handle it. I did not take the second medication. Three weeks later I had the first period I had had in years. After it was over, I was back to my regular self. My conclusion was that my body was trying to have a period. Stupidly, since I like the convenience of Mirena and I seemed to back to normal, I left it in.
A few months later, the feelings both listlessness and "going out of my skin" returned. Needless to say, I rushed to the doctor and had it taken out. She still insisted that Mirena was not to blame. However, since that time, I have heard other similar stories.
My point in telling you my story is so that you can be aware. There is no doubt in my mind that Mirena messed with my hormones causing an imbalance. If it happens to you please listen to your body and have it removed. I hope that your experience will be a successful one. It is for many.
Good luck.
