Pregnant or not?

When is the best time to take a pregnancy test? I didn't missed my period.. My period will start around next week but I'm really not sure what I'm feeling rn.. Not sure if it's pms or pregnant.. My boyfriend and I had sex couple weeks ago..   We used condoms but there was one time he put his d in my v without condoms.. but that was just quick like just 20-30 seconds I guess and he was just gentle on me.. anyway, any advice?
