If a woman is pregnant, she should be highly suspicious of pregnancy when her period is overdue, especially if it is more than ten days, and she can use morning pregnancy test paper to detect it. Because morning urine is concentrated and contains high levels of HCG (human chorionic gonadotropin), it is recommended that morning urine be used to detect it more accurately. Therefore, it is recommended to use morning urine for more accurate testing. Therefore, when the early pregnancy test paper indicates that the color is darker in the afternoon than in the morning, it may be an error, and the test can be conducted under the guidance of a doctor.
