I have had the coil for 6 months and bleed for 2 months continually and now I still bleed on and off and have bad period like pains all the time. Could it have moved? I went to the doctor 3 months ago to have it checked and was told it was fine and that it should settle down soon but it only seems to have gotten worse. Has anyone got any advise? I'm getting worried and my lower back hurts too.
