Mirena for 10 months light periods then extremely heavy period

Savannah
I have had my Mirena for about 10 months and my periods have gotten continually lighter. I recently lost my health care insurance because my Dad lost his job and I'm in college and can't afford it and I'm afraid to go to the doctor for help due to the cost. Has anyone had this problem, and if so what was it and how did you solve it? Thank you so much.
