Birth control pill, no condom? Plan B?

Hi ladies. I’m not really sure if I should get Plan B or not. I had sex with my boyfriend for the first time and we didn’t use a condom the three times we had sex. I’m on birth control (June Fe 1/20) and have been on it for a over a year. I started my new pack on time on Sunday but am I still protected during this time even though I haven’t completed a full week of pills yet. Let me know what I should do!! I’m also not sure if he came inside of me.... I don’t think he did but I would have been able to feel it right?
