Post Mirena Cycle Issue

Anyone else have long cycles and prolonged bleeding after mirena?
I had my mirena removed October 27. I started my period the 29th and had a fairly heavy period for 8 days. My next period started December 1 and has not stopped (that's 28days so far) while it has gotten lighter the last few days it's still disconcerting. 
I went to the doctor last week and have another appt scheduled next week, but would really like to hear from those who've BTDT.
