If you are pregnant, the test results will be the same on the same day, but the color of the test line may be different, especially in the early stages of pregnancy. For women who are in the early stages of pregnancy, the color of the test line will be more obvious when the test is done with morning urine, as the concentration of human chorionic gonadotropin in morning urine is relatively high. If the test is done at night, the urine may be diluted due to the amount of water consumed during the day, and the test result may show that the color of the test line may become lighter. However, as the duration of the pregnancy increases, the hormone levels in the body will also be higher, no matter when the test is conducted, there will be a strong positive performance, and the color of the test line will also be the same.
