has anyone used clear blue smart countdown

So basically my test is a clear blue smart countdown digi, the test came back negative but for some reason I needed to open it up. I've been feeling nauseous, tired and headaches all the time and some slight cramping over the past week. My sense of smell is crazy high! Anyway I opened it up and there's two lines, one very faint and the other clearly there! CB have emailed me back to say it does only pick up HCG hormone, can anyone else see two lines of if anyone else has done this what was your outcome please?
You may need to tweak photo to see second line
