The early pregnancy test has the following clinical results: 1. two red lines with the same color will appear, indicating pregnancy; 2. two red lines will appear, but one of them is lighter in color. In this case, it is possible that the pregnancy is still relatively short, and the test is weakly positive, so it is recommended to check again after three days. If the test is repeated three days later using the morning urine, and it is still one dark and one light, the possibility of ectopic pregnancy should be ruled out. It is recommended to take a blood test for HCG and to check again every other day to make a preliminary diagnosis based on the results.3. Only one red line indicates that there is no pregnancy. In addition, when taking an early pregnancy test, do not drink too much water two hours before, so as not to dilute the urine and cause a false negative result.
