I've had the copper coil for 13 months. And I've been having regular periods since May so 8 month. I've had the pre period cramps but no period. Im now ten days late. I took a test when I was 7 days late and it was negative. So my question is... Is it normal to miss a period when on the copper coil? I've had cramps and sore breasts and a creamy discharge for the last few days. Any comments welcome! ☺️
