TMI picture but I need help

so I'm a day late this month and I've been stressing so much about missing my period. I've had sex 3x this month. all protected and no tears in condom. however I am a day late and I get this in my underwear.  (ignore the yellow. it's just dried blood I couldn't get washed off from another period) anyways. is this a sign of pregnancy? I usually get discharge before my period but I'm freaking out.
