Invalid pregnancy test?

I bought a pregnancy test that came with two tests, both of the tests had a faint negative line Before I used them and no line in the control window. I took one early in the morning and another a couple hours after and they both came out negative and only the second test had a line in the control window but it wasn't a full line and both tests had faint negative lines before I took them.... What does this mean? Are these invalid ?The first test ;
