I have had Mirena since January 2009 and at first I was relieved to see many of my side effects from the pill disappearing. I have more of a sex-drive, no more yeast infections, and over time my periods became virtually nonexistent. However, I now have the worst cramps during my period, and I have never had period cramps in my life! I have gained probably 15 pounds and feel tired all of the time. Worst of all I have turned into a horrible person. My mother prompted me to research this products side effects after she told me I reminded her of my overbearing and irrational grandmother! Saying that she always hates to come home to me as she doesn't know how she will find me! If I will be angry, or happy, or sad, or jump all over her. My fiancee has said the exact same thing. I am now definitely having it removed I just hope the damage has not already been done. AND to top it all off, I haven't even finished paying it off! I still owe money on the Mirena because I was too broke to get regular birth control without insurance.
