I think im protected but not sure

Hey ladies sooo ... Ivr been getting the swing of birth control im on the pill and i started the 15th of February ive had my first period and now im on my second pack with about 3 weeks left , well for the first time my boyfriend finished insdie me last friday and i didnt have my pill wih me until sat. At 1am .... I took two as soon ae i got home ... Would i be protected against pregnancy still or should i have taken plan B..... I continued the regime of my regular dosage sunday and Monday we had sex again and he pulled out but some of his cum ws left inside ... Now i took the pilk early in the day before we had sex about 30mins+ so im not worried about being pregnant from Monday but from Friday im worried we messed up !

Someone help me please .... To Ease this panic ... However im pretty sure we had sex after my fertile days
