HELP , a little stressed !!!😩

Hey ladies , well I wrote a post basically a month ago questioning if I was pregnant or whatever because my boyfriend came home from the military and we had sex twice without a condom but he says he pulled out . But I been having symptoms well a week or two after that. My period is late by two days should I take a pregnancy test ???! The thing is the day we had sex I started my period literally an hour or two after ? Could I still be pregnant ?
