abnormal uterine bleeding
"I had Mirena inserted July 16, 15. I had very heavy bleeding for about 7 days after insertion. Insertion was not painful for me. Had heavy cramping the day of only. I have had some sort of bleeding ranging from a couple spots a day to very heavy for 2 months after. After my period last month I finally quit spotting all together then yesterday came along and I have a super heavy flow period out of the blue. Trying to make it to the 6 month mark but it is definitely annoying."
