What do results of CVS pregnancy test mean?

I just took a CVS pregnancy test...results had a horizontal line in one window and a vertical line in the second window. Does that mean positive or negative??? I bought a 2 pk and threw the box away after I took the first test 3 months ago, thinking I would remember, but I don't. I already called CVS, too, but they were no help because they have more than one home pregnancy test kit (one that shows a + and one that doesn't, but I *know* the one I have doesn't show a + in the results windows, just one line or two).
