Angry pregnant lady

I know my body is going through a lot of changes and I feel like I’ve become off my rocker. My marriage is failing because of it. I am 2 months pregnant and I can’t help but snap at my husband. I am happy then I get super angry. Every one close to me tells me I am not myself while pregnant. I want to talk to my doctor about what to do. Sitting and breathing doesn’t help. Anyone have a recommendation
