I was assaulted

Okay so that happened I got too drunk w the wrong person & he’s a famous guy he has lots of money. He took advantage of my body when I blacked out he may have even drugged my drink. I could’ve got a rape kit done but I’m sure I can’t anymore. I still have clothes from that night in a bag. I don’t think I wanna do anything legally. I should but idk. I went to have sex and drinks w him but I blacked out during sex and he kept assaulting me bc he said in the morning we did things I just don’t remember he said. But that’s bc I past out . Anyways I might be pregnant. Should I just keep the baby from him not even tell him??? He might try and get custody of the baby and I don’t trust him if he can easily assault me like that.

Edit / It wasn’t actually rape bc I did want to have sex with him at first. just not passed out. Idk what happen after I past out. He said he did things to me that I don’t remember all I remember is on my back and past out after.
