Weird discharge HELPP

Why is my discharge orange? There were little stripes of red in there. I found out about it right after I had rough sex with my boyfriend. There was a little bit if blood on the condom itself. My period ended 8 days ago and the last time we had sex was a week ago. Am I pregnant??? Or did my boyfriend just go a little too hard during sex? I never saw the orange discharge again after that. Should I even be worried?
