Late period..test or no?

CB

Was supposed to start my period Saturday 12/31. I had no symptoms leading up to it like i always do (spotting, lower back pain, extremely tender breasts), but I tested on 12/30 evening and it was negative and 12/31 morning and it was negative. It’s now 1/2 and i still haven’t started and have no symptoms of my period coming. Should i test again? Would there still be a chance I’m pregnant even tho I’ve had the two negative tests?
