Relationship problems...

Anyone else pregnant with their first baby and struggling in their relationship with their significant other? Or does everyone else but me get treated like a queen. I feel like he’s challenging me and making everything extra hard for me right now and I don’t know if it’s because I’m just extra tired, extra sensitive, and cry all the time? What can I do to help him? Maybe he’s stressed and doesn’t know how to talk to me...I don’t know but I feel like I can’t handle it anymore.
