am I stressing too much orrr?

had a mishap with this guy, he stuck it in for like 1 min or 2 and thrusted maybe 4 times.. he didn't ejaculate at all and I took plan b.. on my period tracker it said i ovulated on the 21st.. this happened on the 23rd.. but on Glow it said I ovulated the day it happened.. what are my chances and that I could be preggo or am I stressing too much over this.
