I have had the Mirena coil fitted for over 2 years and in the last week have been feeling sick, breasts are tender and now I have abdominal pain, I havent had a period since I have had the Mirena fitted. I saw the Doctor and she couldnt find the threads, I am now waiting for a scan. I have done a pregnancy test and it was negative, but was told to do another one! My Doctor said an ectopic pregnancy is at the back of her mind! I am now worried!
