cd 34 no period

it’s cd 34 and i’ve had literally no sign of my period except feeling some cramps on cd 28. i only had protected sex with my partner where he came in the condom or pulled out on various occasions and none of these times were in my predicted fertile window. i was due for my period today and i have no signs of af except some here and there sore boobs. i took a pregnancy test too because of my paranoia on cd 32 in the afternoon and that was negative. can i be pregnant? or am i overthinking too much and my period will show up? i’m such an anxious person please help me😭
