Possibility of becoming pregnant? Might be a stupid question.

Alright so my fiancé and I had sex on October 6th with a condom but once he finished, he pulled out and it got stuck inside me 😐 I pulled it out and obviously there was some spillage. The thing is I had just finished my period 2 days before and I was still taking my placebo pills (I'm on the pill). We weren't too worried so we went on with our day. Didn't have sex on the 7th but had sex on the 8th and the same thing happened with the condom! My fiancé was a little more paranoid the second time so the next morning I took plan b. My question is when should I be expecting to get my period and what are the odds that I could be pregnant? I know there isn't a definitive answer but I just need some reassurance. My boobs have been feeling tender and webmd is freaking me out.
