Boyfriend Bleeding

While me and my boyfriend was having sex, he was having a hard time getting it in because I was tight. After he had cum, he bled from pushing his skin to far back while putting it in. But, a little of his blood was inside of me and I think a little of his cum as well, but he pulled out. I’m scared that he got a little of his cum inside of me cause a little is still affective. Do anybody think it could lead to me getting pregnant or should I not worry
