abnormal uterine bleeding
"I had my Mirena inserted exactly a year ago at the age of 56. Now 57 and still no menopause in sight. In fact I just got my period today. Granted its lighter than it was before Mirena but out of the last year, I have at least spotted almost every day. June was a good month for me with my first skipped period and no spotting. July one day of spotting. Went for my Pap smear in August, told my GYN that it looks like maybe this thing is finally working, started spotting that night and never stopped for the entire last month. I give up. I do give Mirena a 7 though because my periods are lighter, albeit right on time every month, unfortunately. I will keep it inserted as it is now about what I know."
