I have been sick on Sunday and felt nauseous for 3 days have dirreah and a metallic taste in my mouth, I did a test on clear blue and came back positive 1-2 weeks I went to the dr an hour after that test and she tested negative with a strip test. I also have pain in my pelvis, I’ve had the coil for 3 years. Could my digital test be wrong. . Or did the dr test me too soon. Im worried
