My wife has had the Mirena IUC for five years. She recently, a few months ago, had the old one removed and replaced. Since then, she s had fairly continual bleeding, occurring for about a week every two to three weeks, bleeding after running or exercise, and now has moderate to severe cramping, bloating, headaches, and a general feeling of being unwell, as well as lethargy. Is this normal or is there cause for concern? I can t get her to call her OB/GYN.
