Hello! I Am Currently On Birth Control And Finished My

Hello! I am currently on birth control and finished my period on Friday (yesterday), however, I was not taking the placebo pills and just let my period arrive on it's own. My boyfriend and I had unprotected sex this morning and he didn't pull out in time. However, I did take my birth control pill this morning. I was just wondering if you recommend that I go and get the morning after pill or whether I should still be protected against pregnancy! Thanks :)
