Maybe pregnant? Help please

Had sex yesterday at 4pm (sunday), he pulled out. 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) i get a weird feeling and some white stuff drips out of me and smells like cum. I did not orgasm or cum the whole time we were together .It wasnt very much but still freaking out. Been off birth control pill for a week against my will. We did not use a condom. Im hoping its not his but could i be pregnant?
