please read this I need help🙏🏽

So I started my period today. My boyfriend and I got into a really deep talk and ended up having sex and he came in me and never pulled out and then (without pulling out at all we had sex again and he came in me one more time. He stayed in me for like 3 minutes after that. Should I take plan b ? Or should I be good cause my period just started I also sat up and like felt a lot of it leave so I just don't know.
