Make sure you read the instructions carefully to see what a positive actually is. They are not the same as a pregnancy test. Pregnancy tests are a positive if there are 2 lines at all, whether the test line is really faint or really dark. With ovulation predictor kits, the lines must be the SAME color and darkness. If the test line is lighter than the control line, that is a negative. If the test line is the same color or darker than the control line, that is a positive.
