It wasn't supposed to have any lines when she first taken out of the wrapper. If the line didn't get any darker when she took it, then I'd say you may have had a defective test. Hopefully you bought a package with two in it, since those things can get quite expensive. If not, you may want to go to a local Dollar Tree (other dollar stores tests are different, so if you can, go here) and pick up a few of their baby tests for a dollar. They detect pregnancy as early as First Response's do and are only a dollar. If nothing else, just run back to walmart. Make sure she is testing at the time of her missed period and not too early so that you can get accurate results.

Good luck hun!

it was a faulty test and she needs to retest

ok took another one and it was negative.... do you think its safe to say shes not preggers now that she took it 10 days after her missed period? What should we do next since she hasn't started?

Take another test in a few days if she doesn't start. DO NOT HAVE UNPROTECTED SEX before her next period.
