Everything is going wrong

I don't know if it's the pregnancy , me and my husband have been married for 4 months now and I'm feeling like these last couple of weeks he has just turned into someone I don't see myself being with for the rest of my life. I literally can't stand to see his face , I want him to move out and just leave me alone. We are expecting OUR first child together 4/6 and I'm feeling like when I have her I want to end the marriage. Friends say it's the pregnancy but I feel this hate in my soul
