birth control question

So I went on spring break last week and I had packed away my pills, then realized once I got to my spring break destination I packed them in the wrong purse. So I went a week without my birth control and I had a period for the second time this month. I knew that missing my pills would mess up my cycle a bit but was that normal? I'm not sexually active. Is there a specific way I should catch up on those pills or just take my Thursday pill? (the day we got home from the trip)
