heart problems? blot clot from the pill??!!

Hi I went on the pill (Marvelon) nearly two weeks ago to treat my acne and have been experiencing pain just below my ribs that is getting increasingly worse. My doctor told me that considering my age, my risk of blot clots due to the pill at my age (17) is 9%. Do you think this rib pain could be due to the pill? Should I see my doctor or will it most likely be nothing.
