should I take the morning after pill?!!!!

I have been taking birth control since high school for my irregular periods; I am now in college and just recently started having sex with my BF. Tonight we had unplanned and unprotected sex.... I've been taking my pills correctly on time (combination pill, 2nd week of pack) and he did pull out. We are both freaking out if maybe something could have gone wrong .... should I take the morning after pill?
