It could very well be positive, but just really early, and when your early in your pregnancy, you don't have high levels of hormones like later in pregnancy, but they're definately there, trust me, you'll know. So, don't worry, and take another test in a couple of days.
Good luck,

P.S. Don't forget, if your pregnant, it can be the happiest, and scariest, and hardest thing you ever do, but it will all be totally worth it when you see your baby's smiling face looking at you like you are the greatest person in history.
