Cheating on my hubby dream?

I have had some really awful dreams whilst pregnant and the worst is that I keep having dreams that I’m cheating on him?!

They are so vivid that I wake up feeling sick to my stomach because I’m thinking “did I actually do that to him!?!?”

Also I keep thinking about ages ago when I used to go out partying and he used to stay home about the guys who’d flirt with me and whilst it was flattering, I never flirted back but now I’m second guessing myself thinking that maybe I did which is where the dreams are coming from?

I’ve got severe anxiety from when I was a teen and it’s just getting worse and I can’t think of anything more disgusting than cheating but my dreams and my anxious brain keep trying to tell me that I’ve cheated on him when I know I haven’t!

Any advise because I’m really upsetting myself.
