Am I wrong?😩

Okay so for the past 6 months me and my husband haven’t been having as much sex because of our work schedules and I’m 38 weeks pregnant so when I come home I eat shower and sleep. Well for the past week I have had really vivid and horrible dreams that I wake up crying from about him cheating (probably because I’m on here too much) I’m not the type to look through my husbands phone or get on his phone unless I need too (like if mine died) but I feel like if I look through his phone now and see that there’s nothing bad on it, then I will have peace of mind... is it wrong if I ask him if I can see his phone? And I’m not talking about taking it while he’s in the shower or asleep. I want to tell him about what I’m feeling and everything and ask him if it’s okay if I see his phone (only if he says it’s okay) but I feel like if I see for myself that no he’s not cheating it might make me feel better? I don’t know I feel horrible for feeling this way...
