Only with sample: Even the "cheap" pregnancy tests should be blank until you add urine as directed. Follow the directions and don't wait longer than the given time otherwise the control line can "leach" over and cause the "test" line to show up (a false positive).

When you pee on it.: Use first morning urine and follow instructions for the test carefully.
