Check the Time Machine settings to see how often it deletes old backups. Also, a 128GB drive is on the small side for backups.

How much data is on your Mac? You need space for versioning, how much depends on the type of data and how often it changes but good rule of thumb is your Time Machine drive should be 1.5x to 2x the size of the data being backed up.

If you don't need versioning, look at CarbonCopyCloner.
