I would wait a day and test again. This morning was a thrill to me. The magical Line 2 appeared. The first time in my life. The real one. It only takes about 10 or 15 seconds to show up！ I called my sleeping husband immediately. Too much joy, so I busted into tears... Last year I misunderstood it when the line appeared after 10 minutes. I still remember how disappointed I was at that time when I learned the cold reality.
