Frequently Asked Questions

1. Can a pregnancy test be positive at one week?

A pregnancy test kit may be able to detect pregnancy as early as ten days after unprotected sex, but you cannot trust these results completely. The best time to take the test would be three weeks after sexual intercourse(6)。

2. What should you not do before a pregnancy test?

If you use a home pregnancy test kit, you should avoid drinking too much water before the test as it may dilute the urine and affect the test result(7)。

3. Does a faint line on the pregnancy test strip mean I am pregnant?

A faint line on the pregnancy test strip may represent an early pregnancy, or it may be an evaporation line. The kit detects pregnancy hormones in your urine, so a faint line could mean low levels of the hormone in your body, which may indicate that you are in your early days of pregnancy. It is also possible that the faint line is an evaporation line if you read the test after the recommended time in the instructions. Keep in mind that certain medications may result in a faint line. For example, medicines for infertility may have the pregnancy hormone which the test kit may show(8)(9)。
