Introduction
Pregnancy test strips determine pregnancy by detecting the level of human chorionic gonadotropin (hCG) in urine. After pregnancy, the level of hCG in a woman's body gradually increases. Therefore, pregnancy test strips can be used for an initial determination of pregnancy. It is generally recommended to perform the test around 35 days after conception, 14 days after sexual intercourse, or when the menstrual period is delayed by more than 7 days.

Before use, carefully check the manufacturing date and expiration date of the test strip to avoid using expired products. Follow the instructions precisely when using the test, including collecting the urine sample, immersing the test strip into the urine, and waiting for the required reaction time. When performed correctly, the results are generally quite accurate.
It is recommended to maintain a positive mindset, avoid excessive anxiety or stress, and pay attention to diet and rest to ensure adequate nutrition and good sleep.
