If that bass feels resistance it will let go of the worm in most cases, do not get in a feeling contest with the bass. If you think you might have a hit but are not sure set the hook HOOK SETS ARE FREE. Some of the hits will be the lure gets heavy or you lose touch with your lure ore the line is moving sideways. Also if you are having problems you might fish with braid main line and about 2 or 3 ft flourocarbon leader. This will let you use a rod that is more a medium action you will feel the hits better and your hook sets will be better. Also I set the hook almost as soon as I feel the hit as soon as I think I have a hit I will drop the rod tip down a little and the sweep up to set the hook. Remember hook sets are free.
