Could it be something bad if i have bradycardia?

Maybe: How low is the heart rate and do you have any symptoms at this level: fatigue, dizzy, confused...Some elite athletes can have very low heart rate but for the general population, depending on the factors above, it could also indicate a heart conduction problem (or medication side effects). See your primary care physician who knows you best to see if this is something to be concerned about.

Bradycardia: depends on how slow and what causes bradycardia and whether you are symptomatic
