abnormal uterine bleeding
"I had my Mirena inserted in 2009 and I have yet to experience any major issues. Yes, in the beginning I bled for 3 months with a day or two in between with no bleeding at all, and I had thoughts of getting it removed but never did. It has been very effective and I am glad I kept it in. I have very light cycles now where I might spot for about 3 or 4 days and that's it. I'm relieved that I don't have to worry about unplanned pregnancies and I do plan to get the new one installed next year prior to my current one expiring."
