Pregnancy test

Did anyone Here take A Test with First response and get Negative? Then test with Different brand and get Positive? After I bought First response I started seeing horrible Reviews With them. I got negative with Both first Response. Currently am 10 Days Late for my Period and About 3 Weeks ago had ONE day Where I bled and then nothing else. Now just a Bunch of Thick White/Creamy Discharge.... I would be considered 6 Weeks Today by a Doctor.
