Generally speaking, pregnancy test at night may not be accurate, and it is recommended to use morning urine test for higher accuracy.
After pregnancy, the level of hCG (human chorionic gonadotropin) in the mother’s body will increase. For women with regular menstrual cycles, when the menstrual period is overdue for about 1 week, they can use a pregnancy test stick to test whether they are pregnant, but due to reasons such as drinking water, the urine at night can be diluted and lead to a decrease in the level of hCG, so the test may show a false-negative result, and it is recommended to use the morning urine test to determine whether you are pregnant or not, and it will be more accurate.
It is also possible to determine whether you are pregnant by measuring blood hCG levels, which is more accurate.
However, whether the pregnancy is determined by blood hCG or urine hCG, it is necessary to follow the doctor’s instructions to carry out ultrasound examination at about 40 days after menopause to clarify the normal intrauterine pregnancy, and can rule out ectopic pregnancy, gravida and other pathological pregnancy.
