abnormal uterine bleeding
"I'm almost 24 and have had Mirena for over 1 year now. I am SO glad I was not scared away by all the negative reviews. Sure, insertion hurt just a tiny bit, but it was about 5 seconds of a strong pinching feeling (due to an unusually sharp curve in my uterus) then a few hours of cramp pain, exactly the same as period cramps. If you can handle a monthly period you can EASILY handle Mirena's insertion!

Since I've been using Mirena, my formerly wildly irregular periods have eventually diminished to a day or 2 of extremely light spotting (1 pantyliner is more than enough) every 2 - 3 months. I have not experienced weight gain, acne, or diminished libido, & my sex life is as good as ever! "
