abnormal uterine bleeding
"I was experience heightened mood swing as I entered the menopause phases and my doctor recommended trying the Mirena.  I was warned the first months would be painful then everything kicks in.  I'm five years in and ready to switch out for a new.  I have not a had a period and the mood swings are gone ... my family is very happy too.  I can highly recommend just know the first months are hard."
