I need some serious help!

So I'm 14 and my boyfriend is 16 what happend was that me and my boyfriend were playing around and I have my bf a BJ then we were making out after I swallowed his cum. He also got his cum all over my mouth. Then He was putting his tongue and face all in and around in my mouth and stuff. then he was licking my vagina. I'm scared that I Am I pregnant? I don't want to be pregnant help me please... Any advice on what to do next time? Should he wear a condon when I give him blowjob next time or should I keep mouth wash by my bed?
