A pregnancy test that shows one dark and one light is not a false pregnancy. False pregnancy, as it is called in clinical practice, has corresponding symptoms, such as nausea, vomiting, enlarged breasts, and some people may have a bulge in the lower abdomen. However, the most important thing is that the urine HCG test or blood HCG test is negative, so it is impossible for the pregnancy test to be a false pregnancy. This situation is common for the following reasons: 1. Just pregnant. Because the hormone level has not yet reached the level that makes the two lines of the pregnancy test stick completely dark, so there will be a deep and light, it is recommended to use morning urine to test again after 3 days. 2, due to drinking too much water. This leads to HCG dilution in the urine, there will also be a weak positive situation, so it is also recommended to use the morning urine on the second day to test again. In addition, the appearance of a deep and light, it is likely to be ectopic pregnancy. Therefore, it is important to find out what is the cause of the dark and light color of the pregnancy test. It is recommended to re-test after 3 days. If it is still one dark and one light, it is recommended to go to the hospital to draw blood and monitor the blood HCG, and check again every 1 day to see if the blood HCG doubles and rises, so as to be able to determine the cause.
