Positive test with iud

This morning I felt weird (similar to how I did with my first pregnancy) so I took a test (first response rapid results) and it showed up faintly positive... even my husband says he can see the line and he’s legally blind... so what do y’all think? How likely is it that this is for real? What do I do? Is this an emergency? I am not cramping badly or bleeding heavily.. I just feel very weak and tired and nauseous..

Idk if you can see the second line. It looks like a shadow in the pic.. but it’s pink in color in person.
