Hi R.,
I am sure there have been many women who have had positive results with Mirena. I am not one of them. After I finished nursing my daughter, I had Mirena inserted. Although the insertion is not supposed to be painful, it was painful for me.
After three months of light spotting my periods disappeared. I was told this was not unusual for Mirena and did not worry about it. However after about a year and a half into it, I started feeling out of sorts. I was moody and lathargic. I felt outside of myself if that makes sense. I had absolutely no energy and would sit for hours doing nothing. Sometimes I felt like a raw nerve and that I was going to jump out of my skin. My husband and kids had no idea what was going on and neither did I.
When I went to the doctor she told me that there was no way Mirena could cause this. She said I had to be depressed and prescribed an antidepressant. The pills only intensified my symptoms. I stopped taking them. Three days later I had a period. After my period I was my old self again. What a relief, my body just needed to have a cycle. Because I was feeling back to normal and because it hurt me to have Mirena implanted I did not remove it. Dumb, I know.
A few months later I started experiencing the same symptoms again. This time I immediately went to the doctor to have it removed. Since I have been off of it (years now) I have not had those symptoms. Even though this happened twice and the first time my period had regulated me, the doctor still maintained that it could not be Mirena. I believe whole heartedly it was.
My system is still kind of messed up. And, I was like clockwork before Mirena. Also since my experience I have met and talked with several others who had similar experiences with the jumping out of the skin feeling and extreme tiredness.
Take it for what you will. I know there are many out there who swear by it. You are right to get all the info before hand.
Good luck
C.
