Get Pregnant - 5 Essential Tips

A home pregnancy test determines pregnancy through the detection of the hormone hCG in urine samples. hCG is a hormone produced by the placenta shortly following egg implantation.

With most home pregnancy testing products, the "reaction time" of the test is a minimum five minute interval to verify a negative result for pregnancy. Generally, at three to five minutes, you can interpret the test results. To be accurate, the test results should be read within the reaction time of the test, which is usually at 5 minutes.

Given proper procedure, a home pregnancy test (hpt) is very accurate. Our tests are FDA approved and are over 99% accurate. Correct procedure and observing test-taking tips will maximize accuracy: If a test is not done correctly, it will compromise accuracy. Always check the expiration dates of pregnancy tests! Ours at Early Pregnancy Tests exhibit the maximum-allowable 2-year expiration date.

If you use a home pregnancy test too early in your pregnancy, you may not have enough of the pregnancy hormone hCG in your urine to have a positive test result. Most HPTs will be accurate if you test yourself around the time your period is due (about 2 weeks after you ovulate, or release an egg from your ovary).

With our tests, you can begin testing at 7-10 days past ovulation. A negative this early is not categorically conclusive and does not foreclose the possibility of pregnancy: You can get a negative test result if hCG increases more slowly than "average" or if you ovulated later than you thought you did. If your HPT is negative, test yourself again within a few days. If you keep getting a negative result and think you are pregnant, talk with a health care provider.
