The wiggles are likely gas as it'd be way too early to be fetal movement even if you were pregnant. Looking at a calendar, I am assuming you meant you started the pack on the 30th due to Christmas the week before? This would mean you finish your last row of actual pills Friday or yesterday (figuring based on the extra pills taken), correct?
I will tell you that taking those extra pills did not make up for starting your pack late, so you could still be at risk if the sex was otherwise unprotected. However, try not to stress! If you don't start your period this week, take a test. If you do, then really dismiss the idea.
