Skipping a month!

So I skipped a whole period. I know that having a period means your body is working write going threw the stages it's supposed to. So does this mean something is wrong with me? 6 months ago I skipped a month and then this month I skipped. Does this irregular period mean there could be something wrong with my fertility ? Could I never get pregnant again? Should I go to the doctor? Is it serious or are you all laughing? I'm not sure if it's been happining for ever or if it just started. I only started keeping track for a year now so,, please give me some answers!! Any answer! Give me your opinion !
