Need some input ladies

So on August 25 I had sex and the condom broke, he told me he came in me quite a bit. Note: I am on birth control but I had not been taking it at the same times everyday, so to be safe I took plan b approximately 13 hours after the slip up. On August 26 I was supposed to start my placebos to have my “period” but I skipped those and jumped to my next set of active pills, i’m supposed start my period the week after this next week. Do you guys think i’ll be good? Was the plan B even necessary to take? Please give some input!
