Omigosh! I can't believe all that I am reading!!! I have had the Mirena since Dec 7, 2005 almost 3 full years. I have been feeling icky for quite some time now. I have had frequent headaches, backaches, acne, memory loss, weight gain, mood swings, and most of all feeling like I live my life in a fog with severe tiredness. I decided to come online and look for side affects to the Mirena and found all of you having alot of the same issues as I am. I never thought all the things I have been experiencing were related to the IUD. I am in shock sitting here reading all of your stories. I am a 36 year old mom with 4 children and decided on the Mirena because I get pregnant very easy and didn't want to have any more kids but also wasn't ready to have my tubes tied. I thank everyone for this very informative and eye opening forum. I am going to make an appointment and have my Mirena taken out for good! I will take the risk of pregnancy over feeling like I have for so long any day!! God Bless you all and good luck to you all.
