Period after sex

May 14 th I had sex and still no period . I had light light period but not a full period And last spotting I had after the sex was somewhere around may 19-22 on the last couple days of school . But we used a condom . And I'm not taking a pregnancy test cause I'm scared . But I looked up that stressing over anything delays period . And I've been stressing ever since so. But what do I do.. I'm scared as shit . Am I pregnant ? Please help me in the comments ! :(
