Possibly pregnant? Help

Had sex yesterday at 4pm (sunday), he pulled out when he got close but was still going for a long while in other ways of helping him. Well was wiping wetness most of the afternoon.Figured it wad mine. We fooled around a little more before i left around 8pm (just being touchy and kissing , nothing else) well, 1:30am (monday morning) some white stuff drips out of me and smells like cum. I did not orgasm/cum the whole time we were together. It wasnt very much but still freaking out. Been off the birth control pill for a week against my will. We did not use a condom. Could i be pregnant?
