so you know how if the test thing says negative you should take another one just to be sure? if it says positive should you have to take another one too? can it ever "lie" when it says positive?
FrEe2bMe answered Wednesday March 28 2007, 12:50 am: At-home pregnancy tests have come a long way in the past years, but there are not error-proof. It is very possible to get what is known as a false positive as a result. It is always recommended to repeat the test for affirmation. If you get two different results, a third test is needed. Please keep in mind the at home test mainly search for the most abundant pregnancy hormone, so you're most secure route is to consult a doctor, but the at homes are pretty accurate, so after taking 2 matching tests, you should feel confident in the results. :) [ FrEe2bMe's advice column | Ask FrEe2bMe A Question ]
