help am i pregnant

okay so my boyfriend and i had protected (condom and pulling out) sex three times, these were all my first time. he never came when we had sex, he only ejaculated once out of the three nights when i gave him a handjob.  and after the handjob we didn't do anything else so his cum didn't touch me. this was about two weeks ago and i was supposed to get my period 4 days ago. i'm freakin out because it's usually only one or two days late. and i've been online reasearching like crazy and i feel like i'm getting symptoms for being pregnant or maybe i'm paranoid? what should i do?!
