I have and IUC (minera) and no problems for past two years, but in the past 2wks, I have felt stong flutters in my stomach every where not just lower abdomen . I am tired, my breast hurt, and I m nauseated all the time. I read somewhere that urine pregnancy test will not show if you are pregnant because of the hormones in the IUC. Is that ture, and could I be pregnant. I call my OBGYN and the nurse told me if I m not having any bleeding , everything should be fine. But should I be concerned?
