Is Plan B needed?

Hi guys — sorry if this has been posted about already but I’m kind of nervous. I just had sex with my boyfriend and the condom broke. We realized as he was pulling out that it broke!! I am on Junel Fe 1/20 the combination pill for over a year now. I’m good about taking my pills I’ve just taken some late but never went a day without a pill.

Should I get Plan B since he may have came inside of me? I started a new pack Sunday so I’m on my 4th pill of my 28 day pack. I missed my period last month so I am really nervous about pregnancy (test came out negative) and don’t know what to do... He’s my first boyfriend so I am sorry if this has been asked I just don’t know what to do :(
