Currently, I am using the IUD Mirena device, and it has been 6 years since I ve replaced it. I have not had any bleeding or abnormal bleeding until yesterday, and I am very concerned. I am scheduled to have it replaced in a month, but until then I am a little concerned because of the bleeding, since I ve not had any bleeding at all. Is this normal? I am having lower abdominal pain, but it is not severe.
