If your Mirena expired February 6, I would consider yourself unprotected as far as pregnancy. Also, since the Mirena is expired, you are probably receiving less of the hormone progesterone. Progesterone is the hormone that regulates your cycle and provides pregnancy protection. Your body may be reacting to the decrease of progesterone and you may be experiencing some cramping. You may also experience some irregular bleeding or a period prior to having the next one inserted.
If you are experiencing persistant abdominal pain that worsens, or is accompianed by fever, chills, vomiting or diarrhea, go to your local emergency room for evaluation.
