Pregnant? Yes? No?

Paula
My boyfriend and I had sex a week after my period and we used a condom, but it broke, and we didn't know until after we were done and he had cum inside of me. This happened on November 1st At like 3 in the morning(Halloween festivies and what not) and my period is already 5 days late. I don't know if I'm pregnant or just stressing over finals. SOMEONE PLEASE HELP. 
P.S about a week after the sex I was spotting a little bit so I didn't know if I should have counted that at my period since it was so light.
