Period after a year on Mirena

McKinsie

I have had my Mirena IUD since July 2017, and after the normal period time talked about I didn’t have a period from about Sept 2017. But then last month, I got a two week long heavy flow period with cramps... I have my year check up for my Mirena with my doctor on Aug 8 (my birthday :-/) so I haven’t called him.... Has this happened to anyone?
