I have had my mirena in for almost 2 years now and after reading all of these posts, its really been an eye opener! I bled for 3 months straight, my doc convinced me to keep it in and I did. From then it seemed great. Barely had a period and when I did I would just spot. But now I get headaches frequently and cramping from my abdomen all the way around to my back. I have also had to make 2 trip to general surgery because of severe breast pain and thinking that I had breast cancer. Now, I'm thinking all of this is from the mirena. I have an appointment to have it taken out this month and I cant wait. I have had a decrease in sex drive and have been really tired all the time. I have two children who are 2 and 4 and thought it was due to that, but now I'm thinking its not.
