Pregnancy... anger?

Let me start off saying that I am NOT an intrinsically angry person. I am almost never angry. I do have a history of anxiety and I thought the severity of my anxiety was starting to lead to anger in certain circumstances. But now I’m finding myself angry in many circumstances, even when I’m not anxious! It’s towards family, coworkers, the world... I’m not expressing any of it externally, just experiencing it in my own body, which is probably worse.

Is pregnancy anger a thing??
