help me

hey! so me and my partner had sex on april 5th 4 days after i was done ovulating. we used a condom and he attempted to pull out before he came ( i say attempted because im not 100% for sure).. we ran the condom under water and saw that there was holes in it.. so i then take a plan b 12 hours later. now it’s april 15 and i was supposed to start my period yesterday and im now stressing out. what are the possible of me being pregnant?
