Stressed

Ok I’m having a dilemma and I need advice ..

On the 26th December I had sex with a guy and we used protection, the condom did not split as far as I’m aware because I made him cum orally. I’ve recently joined the gym and I’m going every other night and sometimes everyday which is something I haven’t done in 2 years. My period is 24 DAYS LATE (I know wtf) but I haven’t done a pregnancy test... I’m too scared! Should I do one just in case or will it be pointless? Is there anything else which can delay a period??? Stressing so much!
