Different brands instruct the woman to wait different amounts of time after putting urine drops on the kit. Once the time has passed, the user should inspect the "result window." If a line or plus symbol appears, you are pregnant. It does not matter how faint the line is. A line, whether bold or faint, means the result is positive. Most tests also have a "control indicator" in the result window. This line or symbol shows whether the test is working or not. If the control indicator does not appear, the test is not working properly. You should not rely on any results from a faulty kit.
