should i be worried

i had sex last monday and i was a little tipsy but i remember everything, we used a condom and he came outside so i was ok chillin & i even sent him a text asking & he said the same thing, so i wasn’t worried at all but today i went to the bathroom, cleaned & i saw very little spotting of blood like pinkish even, so i am now worried, i don’t know if it’s normal or maybe ? i don’t even wanna think about the possibility of being pregnant, my parents would kill me.
