Missed two days birth control, unprotected sex, could I be pregnant?

Patient: I had unprotected sex December 23rd, 2011. Prior to that I missed 2 consecutive pills but took 2 the following 2 days to make up for it. I had sex on the first day I took two pills. I had unprotected sex again on January 5th, 2012. My period should be coming any day but I’ve been really paranoid about being pregnant. What’s the possibility that I am?
