First check the expiration date on the packaging and make sure it is not finished,
For best results, try to test the first thing in the morning, when your urine is most concentrated. Read instructions carefully as they vary with different brands.
Some require you to urinate in the cup then, using the supplied dropper, place a small sample in the test as well. Let others pee you directly on the test device. Some will let you do either.
Tests also vary in how the results are displayed: for example, some show pink or blue lines on the test strip, while others reveal a red plus or minus sign in the frame. Many tests now have digital presentations that tell you the sense of whether you are pregnant or not. Most have a control pointer (often a second line or code) that is supposed to indicate whether the test is valid.
If the test shows a negative or a weakly positive result, wait a few more days or a week and try again if you still have not had a session. One possibility is that you bleached later in your course than I thought, and took the test too early to get a positive result.
Whatever you do, do not assume that one negative result means you are not pregnant. If you do not get your period as expected, remember that you may still imagine. (It’s not the time to explode on excessive drinking or do other things that are considered unsafe during pregnancy.) If you still have not got your period or positive result in the last week or so, make an appointment with your doctor to find out why.
Is it possible to get a false positive result?
False positives are not common, but they do not occur under certain conditions, such as:
