Also, keep in mind that you're database is probably in full recovery mode. what this means is that, as data is being inserted, updated, and deleted in the database, sql server logs it in the database log. This log can become quite large on a busy database. You can reduce the size of the log by performing full backups. Remember, the point of the log is so that you can do log backups and do point in time restores. If you're not doing this, or don't need to do this, you might consider having the database turned to simple recovery mode.

Do not shrink the database during maintenance. There is probably no other more damaging action you can do. Read more at Auto-shrink – turn it OFF. IF a database has grown to a certain size, then it will likely grow back if you shrink it. Shrinking the database is tremendously damaging to the index fragmentation and will slow down your reporting and analytic workloads. Once shrink, when the database will grow back during normal operations the auto-growth events will interrupt and freeze the database during the growth.

There is one thing to shrink a database that had got out of control due to some rogue action that increased it. But to have the shrink in maintenance task means you will constantly do it on a scheduled interval, and this is very bad.

There are a couple of things you can do the check on this. In SQL Server Management Studio (SSMS), Object Explorer, right-click on the database name and select Properties. On the General tab you'll find the Space Available value. Is there any available space?

Note that the space available includes space in the transaction log file. You need that space, so you don't want to shrink the database too much.
