Hi Tracey -
Has your term started yet? If not, your courses may not be accessible or possibly even published yet. It's okay. If you don't see your courses by the first day of the term, you can ask your local Canvas Support for help. (How do I get help with Canvas as a student?)
If you want to double-check your courses' availability, click Courses then All Courses to see the list of the courses that are available to you. Any course with a star to the left of its name will be added to your dashboard.
Here's some more information that may be helpful: https://community.canvaslms.com/docs/DOC-10539-4212724703
