Could I still get pregnant?

So I went to work this morning and for lunch, my boyfriend came and picked me up. Neither of us had money for fast food with us, so we went to his house to eat something over there. Well, we ended up not eating. We ended up having a quickie because I had to get back to work. So, he came in me, and after that, we hurried and got dressed, and he took me back to work. I felt really wet down there and it bothered me the whole car ride. Once I got to work, I went to the rest room and cleaned myself off. I don't think if I cleaned off some of, or most of, the cum. If I did, could I still possibly get pregnant??
