When are you protected?

Been on yasmin for months, I went off it for my weekly break, but didn't go back on it again until 12 days later instead of 7 days as I had a terrible headache and didn't want it getting worse by taking my pill, which is known for their headache side effects. 
ANYWAY..  I was back on it again for 2 days after being off it for 12 days. My boyfriend ejaculated inside me (mistake) am I protected? Or will I have to get the morning after pill?
