Am I pregnant🙄

So I had sex close to the time I ovulated then about 8 days later October 29th I bled pink it stopped after a couple hours and turned brown then stopped completely . My period wasn’t due until the 3rd of November and it says it should end the 6th ( my period is only 4 days long max) and its now the 7th and still no period . Mind you I never miss a period or am late . My bestfriend said stress but im not stressed at all tbh. Should I take a pregnancy test ? (Ive also been feeling sick , real tired , slight cramping )
