Am I pregnant?!?

I was messing around with my boyfriend about a week before my period was supposed to start and I gave him a blowjob/handjob and  a little bit might have got on my finger but I sucked it off. Then later I was masturbating and I touched my clit and outer lips with that hand. I'm only 16 but my period was supposed to come yesterday and it didn't. What are the chances of me being pregnant???
