It is possible that your period is late because you came home from college. There are a few reasons why this could happen.

* Stress: Coming home from college can be a stressful time, and stress can cause your period to be late.

* Change in routine: Your body may be adjusting to the change in your routine, which can also cause your period to be late.

* Travel: If you traveled home from college, the travel itself could have disrupted your menstrual cycle.

It is also possible that you are pregnant, even if you think you are not. If you are concerned about pregnancy, you should take a pregnancy test.

If your period is more than 10 days late, you should see your doctor to rule out any other potential causes.
