I have had my mirena IUD in place since December 2003. I have had bloating, mood swings, anxiety, headaches, dizziness, no period or so minute that it doesnt even stain a pad, I have gained weight and I just feel plain yucky. Needless to say, after reading the side effects of all of the women on here, I am having this checked out and thank you all for letting me know that I AM NOT CRAZY like my husband thinks.
