Ok so I had sex december, I used protection. I got my period early, jan 7 it lasted 6days. Thought it was spotting. My tummy feel wired. Am I pregnant?

Abnormal period. If your period was abnormally light in january, and you are having abdominal symptoms, you should definitely have a pregnancy test. Birth control methods can fail. You should also talk to your doctor about your symptoms whether or not you are pregnant, and whether your current method of birth control is adequate.
