URGENT PLSSS help; how high risk?

Hi everyone!
I'm 24, my period started oct 29 and ended mov 2nd. Not knowing much about fertility I had sex with my boyfriend on Nov 3rd and 4th and he ejaculated in me twice.
Using this app now I discovered that my fertile days were apparently from the 8th to the 14th. This app says I was 9% high risk for preggo.
Not looking or a baby right now should I be worried?
Was low on funds and took plan b pill on nov 10 I have been having stomach pains and cramps all this time
