Angry about being pregnant?

My SO and I have been TTC for 3 months. We both have daughters from previous marriages. I got my BFP a couple weeks ago and I'm now 5 weeks. The past few days I have been so angry with him. I don't want him to touch me or talk to me. I'm angry that his life is continuing without interruption and I'm stuck throwing up at home. I'm an actress, and I can't work while pregnant. I got so angry this morning I told him he could have the baby once I deliver and I want out of the relationship. Everything was fine last week, and now I don't even want to be with him? I can't even pinpoint exactly what I'm mad about. Do I really want to leave him, or are these hormones already making me crazy?
