I am two days late for my period, could I be pregnant?It is possible, yes, but that doesn't mean you definitely ARE pregnant. Get tested as soon as possible. Pregnancy hormones begin flooding the body after conception and typically show on a test once you are late for your period. However, your late period may simply be the result of an especially stressed time-period, over-exercise, past use of certain contraceptives or other simple causes. Some women are always irregular in their cycles regardless of outside factors. See your doctor for concerns about menstrual irregularity when pregnancy is not indicated.
