How often is first response pregnacy testing usually right?

I was just wondering how often is First Response Pregnacy Testing usually right? That is what I got my girlfriend. I have heard about some test that were wrong and when it said negative it was actually positive and things like that. Just a quick simple...

question. She is like 7 days late for her period by the way... the thing said test said negative too

I'm not sure, I never used them. You should either buy another one or go to a clinic - they usually have free pregnancy tests.

I dont realy have an answer to your question but i justed want to let you know i know how you feel. Im a few days late and im about to flip out cause im still in school so is my boyfriend we still have so many plans to fullfill and neither one of us can support a baby. I want to take a test but at the same time im scared to cause i dont want to find out that i am (if i am) till i have to you know. Im just realy scared. But i read that they are pretty accurate but you might want to cakk the maker and ask them or go to a health deparment. I hope it works out for yall.

I don't know...but iam trying one soon..ill let you know Lolz
