Confusing pregnancy test results.

[CrystalAujhae]

I have recently taken a cheap dollar store pregnancy test. It was the kind where you use a dropper to add a few drops to the test and then you get your result. Well I used the test and when the time was up i noticed that the test strip had turned pink but not in the results window. I took the casing off and the strip was pink before the results line and after the results line as well as the control line. I took two tests ans it happened both times. I have taken these tests before and got negative results and when i took the casing apart there was never any pink anywhere. Has anyone ever had this happen?  Or perhaps know what it is? I have been having pregnancy symptoms as well as what i believe has been implantation bleeding. I am going to buy better tests but in the meantime. Does anyone know whats going on?
