A pregnancy test with 2 bars is not a sure sign of pregnancy. The two bars on the pregnancy test indicate that the HCG concentration in the urine is elevated beyond the normal range. If the color of the two bars is darker, it usually may represent pregnancy. If the color of the two bars on the pregnancy test is darker and lighter, it may be a false-positive situation, and there is no pregnancy, or it is due to the fact that the pregnancy time is too short, a kind of reaction is revealed. So two bars on a pregnancy test does not necessarily mean you are pregnant. To determine whether you are pregnant, you usually need to go to the hospital to get a clear blood HCG concentration as well as an ultrasound to see if there is a gestational sac in the uterine cavity, which can determine whether you are pregnant. In order to ensure the accuracy of the results, you can go to a regular hospital to have a relevant examination to determine whether you are pregnant or not.
