I have had a Mirena IUD for about a year

Patient: I have had a Mirena IUD for about a year now and I started getting periods after having it for about 8 months they stopped then came back about 5 months after that and they are getting progressively worse. I have never had cramps before but now they seem to be getting worse and worse with each period. Now I am bleeding again and it has barely been 2 weeks.

Doctor:
