Husband raped me? What to do?

My husband was out late one night with the boys, we have no kids (yet). He came home and I was asleep and he began having sex with me. I woke up and told him to stop but he didn't. He was really drunk, like I've never seen him before. I slept in the guest room that night because his actions scared me. When he woke up to go to work the next morning he came in to say goodbye and has no recollection of the events. Should I bring it up? I'm kind of nervous now I might get pregnant too because we've been waiting to wait until we are vested at work. We've been using condoms only, which I doubt he used that night. It a week ago and I haven't brought it up to him yet. So should I or no?
