I took plan b but i have a question..

my boyfriend and I had unprotected sex a day after i ended my period. so as a precaution we went and bought the plan b pill the morning after we had unprotected sex. well i took the pill mid day and later at night at around 9 PM my boyfriend and I got in a make out sesh and I got fingered. will this screw up anything down there for the plan b pill to work or am I overthinking and stressing myself out?
