Digital tests, on the other hand, are less sensitive and may require more hCG, so you should wait until you haven't had your period to do this type of test. So, digital tests take the guesswork out of analyzing a pregnancy test, but they're not necessarily more accurate. You can do the test 5 days before the lack of menstruation. The best time to take a pregnancy test is when your period is late.
However, some home pregnancy tests say they can detect whether you're pregnant or not up to five days before your period starts. How do they do it? Home pregnancy tests use the hormone human chorionic gonadotropin (hCG) to detect pregnancy, and some are more sensitive to hCG than others. That's why some tests work sooner when you have less of the hormone, while others don't test positive until later, when you have a higher amount. As stated above, the new digital tests will even tell you on a clear digital screen if you are pregnant or not.
