Absent period for a month after Mirena

Patient: Is it possible that after being on mirena since april 12th 2011 and having completely normal periods, same time each month since, that my period can abruptly stop?

Doctor: It is possible to experience menstrual irregularities after mirena insertion. However, I would still suggest for you to see your doctor to make sure there is no concurrent pregnancy which requires removal of the IUD. I hope the answer helps, take care.
