Aunt delayed seven days at noon test is not necessarily accurate, it is recommended to choose the morning urine for testing.
Aunt refers to menstruation, women of childbearing age after intercourse during ovulation, due to the relatively late appearance of HCG (human chorionic gonadotropin) in the urine, so you can use the early pregnancy test paper to detect whether you are pregnant or not on about the 10th day of the menstrual period, due to the concentration of HCG in the morning urine will be a little higher, so it is not necessarily accurate when the test is taken at noon of the seven days of delayed menstruation and it is recommended that you choose to take a test in the morning urine.
When women with regular menstrual cycles delayed menstruation to suspect the possibility of pregnancy, especially overdue more than 10 days, when the early pregnancy test paper test negative, can be an interval of 1 ~ 2 days to choose the morning urine and then retest, if necessary, need to go to the hospital for blood HCG test to confirm. When the result is positive, ultrasonography should be performed under the guidance of the doctor to confirm intrauterine pregnancy.
