pregnancy

so me and my boyfriend had sex the 27th and we didn’t use a condom & he said he was about to cum & i told him to pull out but like it took him over 5 seconds and then i always worry about being pregnant after not using a condom but now like i have all these symptoms and my period is supposed to start in 6 days should i wait to see if i get my period ? or should i take a pregnancy test . i don’t know if i’m just over reacting?
