Yes you are correct. But I swear the ONLY time a negative frer had turned positive a few days later was when I was pregnant. And I scrutinize those suckers so no chance I missed a faint line within the window. Also...don't ask why I don't toss my used tests. I usually just angrily shove them back inside the box. At least in that one instance it paid off.
