I have recently bought a home pregnancy testing kit i can know as soon as possible if i am pregnant.why do they suggest testing twice?
The new tests are so accurate that they can be used immediately a period is missed.However,although the test is accurate the certainty of a pregnancy continuing is not. Many pregnancies,perhaps as high as 10 percent ,fail to implant properly. Although your test can be positive immediately your period is missed, a retest two weeks later may give a negative result.This is why most tests advise that your wait until you are at least five to six weeks away from your last period. Even with this precaution it is important to remember that home tests have a failure rate of one in every 100.
