It's riskiest when you miss pills near the beginning or end of the pack. It is unlikely but you could have ovulated in that time and having unprotected sex could have gotten you pregnant. You should have used protection when missing that many pills for atleast a week after. Also taking 5 pills in one day can't be good for you at all :S You must have felt sick all day. Anyway I doubt you are but if your period is late take a test. If you ever miss 5 pills again you should contact your doctor for advice of what to do.

You should only take 2 in a day and that is only after missing the day before not 4. I agree with the above comment if it happens again talk to your dr.
