I just found this site and it has been very helpful. I am writing because I have had the Mirena for almost 1 1/2 years. Up until this month I have loved it and had only great things to say about it. In the past 3-4 weeks I have had a complete change of heart. I have gained 5 pounds in the last two weeks and have been a complete mess. I have the same symptoms that I did when I was pregnant. I have taken a pregnacy test and it was neg. It seems like most people had problems from the beginning, has anyone experienced what I have?
