How many days after a missed period can I use a pregnancy test stick?
Disease description:
My menstrual cycle has always been quite regular, but this time it's delayed. I would like to know how many days after a missed period I can use a pregnancy test stick to check if I'm pregnant. Will the result be inaccurate if I test too early?

The normal range for the menstrual cycle is 21 to 35 days. If the cycle is relatively regular, a pregnancy test can generally be performed using a home pregnancy test stick approximately 7-10 days after the expected menstrual period has not occurred.
After the fertilized egg implants in the uterus, the body begins to secrete human chorionic gonadotropin (hCG). Pregnancy test sticks determine pregnancy by detecting hCG levels in urine. Usually, 8-10 days after conception, hCG levels reach a concentration sufficient for detection.
To increase the accuracy of the test, it is recommended to use the first morning urine, as hCG concentration in urine is highest at this time and more easily detected by pregnancy test sticks. It should be noted that every woman's physical condition and pregnancy status may differ; therefore, when using a pregnancy test stick, it is recommended to follow the instructions provided in the user manual and consult a doctor when necessary.
If you suspect you might be pregnant, especially if the test result does not match your physical condition, you should seek medical attention promptly for confirmation of pregnancy.
