My daughter is 47 years old, and her period is two weeks late. how likely is it that she could be pregnant?

Unanswerable: Unfortunately there is not enough information or history about your daughter in your question to give you any valid answer. But my first response, given her age, is that she is most likely menopausal or getting close to menopause.

10%: More likely she is transitioning to menopause. Is she having hot flashes? With that being said sometimes women can get pregnant at that age.

Late period: She may be entering menopause rather thanbeing pregnant.

Pregnant: She is more likely to be entering menopause than being pregnant. Invest in a pregnancy test to see if she might be pregnant.
