Am I Pregnant!!!! Please Answer!?

ok well i went out with this guy and we were making out and he put his hand down my pants and fingered me and i put my hand down his pants and gave him a hj at the same time. then we stopped for a minute to undo the on on his pants. and there was a tie on his pants that he was trying to untie. i noticed on his underwear a wet spot. i really dont remember if the tie was on the wet spot at all. then he fingered briefly and we stopped. when i got home i didn't immediately wash my hands. i first went to the bathroom and had to shave my bikini area. Is there any chance i could be pregnant???? i ended my cycle 7 days before this event. This whole thing happened saturday at 1 am. Am i pregnant??
