If the pregnancy has reached a certain time, the HCG level in the urine will appear at a certain concentration in the morning, noon and night, so the early pregnancy test at night is also accurate and will also show a positive result. However, if you are just pregnant, only the morning urine contains a higher level of HCG. It is recommended that if you use the morning urine for early pregnancy testing around 35 days after menopause, the positive rate will be higher. It is recommended not to drink too much water two hours before urine retention, as this may cause dilution of the urine and lead to a false negative result in clinical practice. If you have a history of menopause and the first time you test negative with the early pregnancy test, and you have not yet had your period, it is recommended to test again with the early pregnancy test 3 or 5 days later.
