Plan B or Pregnant?

So I had sex w my bf on 10/1 and 10/2 which was 4/5 days after my period ended. We used the withdrawal method but due to anxiety I took a Plan B pill around 5 hours after sex. We had sex again on 10/8 which was my predicted ovulation day according to the glow app. He did not finish in me. I have been on BC for years and haven’t missed a pill. I take them roughly around the same time at most hour/ hour 1/2 late. I am a week away from my period and I have been experiencing sore nipples like crazy. Is there anything to worry about? This is my first Plan B experience. Should I be worried about pregnancy?
