Crazy dreams... need input, lol.

I'm not sure what to make of this one, lol. It could just be one of those crazy weird pregnancy dreams that have no meaning, or my subconscious could be trying to tell me something, lol. I'm on the fence with this one.
Last night I dreamt that SO and I were living in this really beautiful mansion. Well there was this lady that always ended up in our house somehow, and this infuriated me. I was about to shoot her. Like this crazy lady would knock on the door, but would end up coming in through a window or some stupid smurf if I didn't open the door and let her in. Well, come to find out, she and my SO are having sex. Frequently. I'm not upset about him screwing her, I'm upset about the fact that he refuses to wear a condom with her. I'm all worried about catching smurf (and yes, I am pregnant in the dream), and he just blows me off. I start crying about how it's not fair that I've done all this to change myself (I was not a monogamous person for a long time) so that I could be with him and only him, and he's off smurfing some other girl and won't even wrap up so that the mother of his child doesn't catch anything.
Now, I know full and damn well that SO is not cheating on me. I know that he loves me and would never do anything like that to me. So I don't know if this is because I'm afraid of something IRL or if it's just a crazy dream. What do you guys think?  

Pregnant people can have lots of crazy sex dreams. I can't tell you how many dreams I've had this pregnancy of my SO cheating on me with girls! But I know he isn't. It's just all the pregnancy hormones making you nutty while you sleep lol
