A pregnancy predictor or home pregnancy test (HPT) is convenient and easy-to-use because it can be done at home. It's a qualitative type of test that works by showing one line or two, depending on whether you are pregnant or not. If two strips appear, it means that the result is positive, which is to say, that you're pregnant. If not, the result is negative.
