Pregnancy Scare

So ive been on birth control for the last year. this month i stopped. i havent been having any sex all summer so i was like what's the point. my period arrived randomly on june 7-11th. few days later i had sex where the condom broke. i took plan b. week later i began my birth control due to sex possibilities. I was on the pill for 7 days had sex twice. yet, unprotected, yet very successful pull out. my period is suppose to be due the 5th according to some period trackers. yet im obviously just scared to death. im aware of precum and the importance of birth control & will start & never stop again if i get pass this. i just would like your thoughts on my situation. how likely do you think i am in fact pregnant?
