Why did you take 4 days worth of pills in one day (Friday) and 3 days worth the next day(Saturday)? Did your doctor or the pharmacist advise you to do this or did you think of this yourself? By doing this, you gave yourself two days of a birth control overdose.
If you have been taking your pills regularly, one pill each day at the same time each day, then, you are protected from getting pregnant. What do you mean by unprotected sex?
