8 Months postpartum and still spotting + IUD

Liv
Okay Ladies, I need help or any tips on the topic. I am 8 months postpartum(3/21/16) and had Mirena place in early June. I am STILL spotting. Went to see OB, she said it was extremely normal to spot up to a year after it was placed. So basically what I am asking, did this happen with anyone else?!?
