How many days pregnant can be detected with a pregnancy test stick

Pregnancy test can be used to detect pregnancy around 10-14 days.

After conception, the body gradually produces human chorionic gonadotropin (HCG). Generally, HCG levels begin to rise around 10 days of pregnancy, which may be detected by pregnancy test. As pregnancy progresses, HCG levels continue to rise, and pregnancy test results will be more accurate. However, each person's physical condition varies, and HCG secretion rates and levels vary. Some women may be able to clearly detect HCG levels as early as 10 days of pregnancy, while others may need to do so later.

For more accurate results, it is recommended that you delay your estimated menstrual period by a few days. If the test results are negative but pregnancy is still suspected, you can test again a few days later, or go to the hospital for a blood test, which can detect HCG levels earlier and more accurately.
