I had my copper IUD replaced with Mirena because the copper cause too painful of cramps during my periods. Now that I have gotten Mirena in, my cramping has lessened dramatically. However, I have been bleeding for 3.5 weeks. I had it inserted and didn’t have bleeding for the first week, except maybe a little bit of spotting. After that, the bleeding hasn’t stopped. I just don’t know if this is normal or if I should get it checked out. Has anyone else experienced this?
