Plan B while on bc pill?

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 last night 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 Sunday (I take it at 1:00 but accidentally took it like 30 minutes late is this bad?) but am I still protected during this time even though I haven’t completed a full week of pills yet. I’m only on my 5th pill of my new pack for this month. 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?

**I also took Plan B last month so I’m not sure if that could cause any issues**
