Raped by bf I'm 16 and he's 18

I was raped by my bf this morning.. I was hanging out with my bf at his house after having breakfast with him, and he started feeling on my thigh so I took his hand off of it, that's when he started asking me for sex repeatedly. I got up to try to leave and he grabbed me and forcefully pulled my shorts down while I punched, scratched and kicked him. I scratched him to the point where I got his blood under my fingernails and I'm a virgin so it really hurt me when he pushed himself into me I was really screaming hoping someone would hear me. I'm scared I might be pregnant because he finished himself inside of me then threw me out of his room and told me to get out and if I tell anyone he raped me then he'd kill me. As soon as I got home I told my mom I was raped she immediately took me to the hospital, she asked me if I knew who they were and I didn't say anything. I'm so scared. I'm at the hospital right now.. I really needed to get this off my chest. I'm scared to tell on him idk why😭

UPDATE!!!! : I told the nurse and my mom who raped me, they arrested him and the officer who came to question me spoke with my mom in the hallway and she says that my bf wants to sue because he told the police I willingly had sex with him..

Update: i have to face him in court August 7th. They're holding him in jail until then. Idk why the rape kit wasn't enough because it's clear signs that it was rape. He's going on trial, he has a lawyer now too and they're making me prosecute him. I definitely pressed charges. Wish me luck.

Update: court went well, I prosecuted him and the judge sentenced him to 10 years and afterwards he'll be released on parole. My mom is working on getting me a restraining order against him, but there's a chance I might not get it if they don't think he'll be considered a threat to me. Thank you guys so much for your support I really appreciate it. That experience had scarred my trust in guys sadly..
