Faulty Pregnancy Test

I've been experiencing a lot white discharge. So I took a pregnancy test today and when I was done I swear it was going positive then changed to negative. I checked the expiration date and it said 2013, also when I first took it out of package it looked like there was a faint negative line to begin with. Retesting tomorrow morning, but could have it been a faulty pregnancy test?

Who knows. At home tests can give false results. Take it again in the morning, but don't look at it until time is up. You can drive yourself nuts trying to interpret the intermediate stages. If it's positive, you should still get a blood test from your doctor to confirm.
