Do I need to have my heart murmur checked regularly?

It depends. Heart murmur is not a diagnosis. You need to know what is causing your murmur.
Depends on the cause. Many murmurs are harmless. Some just need to be watched, some reveal underlying problems that can be corrected or helped. The doctor who found the murmur can tell you which you have & what you ought to do. If you no longer see that dr, see a new one to ask. Then you can relax.
