Help!

Okay, so I've had symptoms of pregnancy, and terrible cravings for the past week or two, I've been craving mcdoubles and orange juice, I pee at least 12 times a day, I'm emotional, moody at times and sore breasts along with others... I took a test Saturday morning, it came back negative, but it was also 9 days before my monthly.. Could it be a false negative due to testing too soon?
