Moody..worse at night anyone else?

So I'm having trouble with my emotions. It's my first (unplanned) (still grateful) pregnancy and the hormones are making me feel just not myself and at times even angry. I feel so irritable and it's the worst at night sometimes. In bed I can feel waves of Rage come over me, especially if my boyfriend has tuned me out (as he should when I'm ranting) but I start word vomiting! I am so not proud of those moments. Anyone else? Anything help?
