There are a few things that can cause a false positive. A recent miscarriage, certain fertility drugs. The article at the following link has some great explanations.

There is no food*, no alcohol, no contraceptive, and no illegal or over-the-counter drug that can mess up your HPT results, and semen cannot affect the test. The only drugs that can affect pregnancy test results (in the form of a false positive) are prescription drugs that contain hCG (such as Profasi, Pregnyl, Ovidrel, etc.) They are prescribed for fertility treatments or other "female problems." If you are taking one of these drugs, ask your doctor how soon you can use a pregnancy test (different doses require different amounts of time to leave your system, so what works for one woman might not work for you.) *Food itself does not cause false results, but can affect how much urine you have and how dilute it is. Eating salty chips and drinking caffeine all day will result in more concentrated pee, whereas gorging on watermelon and ginger ale will result in lots of very dilute pee. Very diluted urine during very early pregnancy may result in a false negative. For best results, pee in a cup first and make sure your pee is medium to dark yellow. Lastly, if you have been pregnant recently, it's possible that the test is detecting residual hCG. However, if a pregnancy ends early on, it's unlikely that hCG will remain in your system very long, so most women have nothing to worry about here. (It's extremely common for women to conceive immediately following an early miscarriage; the body is "primed" for pregnancy, so to speak, and elevated progesterone left from the miscarriage gives the next embryo a great shot at a healthy implantation. So, most women really are detecting a new pregnancy.)

However, the more hCG you had in your system when the pregnancy ended, the longer it will take to dissipate. HPT's can even detect residual hCG for up to 6 weeks following a full-term birth. It's a possibility you should keep in mind if you get positive HPT results soon after a previous pregnancy ended.

A recent miscarriage or pregnancy, certain fertility drugs that contain pregnancy hormones, or a defective test.

If you're really not sure, I would buy another test of a different brand and test again.
