How to structure dashboard with schedule

So, in my current design I have something like this:

I have a dashboard that has a menu with a couple different options. In the 'home' option the user can see a schedule with their appointments if there are, the appointments waiting for confirmation, the next appointment and the last appointment in order to rate it. When the user clicks on start timer a timer stars and then changes the last appointment to the one that had previously had the timer.

Am I showing too much information to the user? Should the schedule be shown separately and include clicks to go see it whenever it would make sense to? Or should I have a even more reduced version than this schedule and then another schedule but with more functionalities?

Thanks!
