Need help ladies

I've tooken 5 test and they all came out with a vvf second line in the same spot. Theres no way that they would all come back with a second line in the same excalt spot. Is this my postive?? I need y'all's opinion. I've heard of evaps and stuff like that but there's no way that 5 test would come back all the same way unless it's postive right?
