This could be because you've experienced break through bleeding or that you are pregnant. Its most likely break through bleeding though if you haven't missed any pills. Break through bleeding usually occurs because the pills aren't working properly or the hormone dosage isn't high enough for you. See your doctor about increasing the dosage or starting a different BCP.
