am I pregnant?

My boyfriend and I had protected sex last night, however the condom broke. But he always pulls out even with the condom. He said the condom broke right before he pulled out and after he pulled out he came. *this next part may be TMI* When I went to retrieve the peice of the condom that was still inside of me, I found that I was dry even in every nook and cranny (yes I know being dry during sex is no bueno and that is something me and my OB/GYN is working on). My periods is about to start in a day or two. I know I'm probably not pregnant but I stress about everything and I really need reassurance. I'm 18 and starting college in August and I do not need a child right now.
