What do you think???

A week ago my boyfriend and I had unprotected sex (stupid, I know) however I'm on the pill but my mom said the pill can actually still have me be fertile. I took plan b (take action) less than 20 hours after he told me he finished outside of me but I got back on, he said he cleaned off but I am also waaayy above the weight of recommended use...so should I be worried about pregnancy? Picture for attention....
