Period is late. Should I be freaking out?

So last month I skipped the sugar pills in my BC pack. We were on vacation and no one wants shark week on vacation. Well earlier this week I got caught up in life and forgot about a few pills so I spent the week playing catch up. I took my last pill on Friday and have been on the sugar pills since Saturday and Aunt Flow still hasn't shown up. Could it be because I got messed up on my pills last week? Usually if I miss a pill or two I almost immediately have break through bleeding so now I'm freaking out cause I've got nothing so far. Not a cramp not a symptom... Nothing. Help
