False positives are very unlikely, like already said above, since you have to have the hcg hormone in you urine for the test to show positive. Congratulations! You're pregnant ;-) hope all goes well for you! Hugs
Chances of a fake positive are really low.. They will only display positive if there is enough of the hcg hormone in your pee. False negatives are a lot more likely to happen cos you might not have enough of the hormone yet. Hope that makes sense and congratulations!! :)
