Pregnancy sticks can be taken on the sixth day after your period and are most accurate after the eleventh day after your period.

Always follow the instructions on the box and make sure the medication hasn't expired. Take a pregnancy test first thing in the morning, before your period has been delayed for at least a week.

Hormone levels in a woman's body vary. Despite a negative test result, if you still have some of the symptoms of pregnancy, you should take another pregnancy test after a few days. Different brands may produce different results in women. If you doubt the accuracy of that brand, try another one.

Cautions

1. Try to Use the first urine of the morning for testing, as this is when hormone levels are most easily detected. If this is not possible, make sure the urine is in the bladder for at least four hours before using it for testing.

2. Don't drink too much water in order to increase your urine, as this will dilute the hormone levels.

3. Read the instructions carefully before starting the test and follow each step exactly.

4. Some medications may affect the results of the test, so be sure to read the label instructions carefully.
