False Positive

Monique
Do you guys think it's possible to have a false positive? I've only taken one pregnancy test and haven't gone to see an obgyn yet... and the test I got was a dollar from the dollar tree... but it immediately read positive I didn't even have to wait 3 minutes... I really want to be preggers I just don't want to be lead on by a false positive that will seriously hurt my feelings lol but AF was suppose to come on the 23rd of Dec but she never came I tested on the 30th and got a positive...
