Really upset and 6 weeks pregnant

So my husband and me just got into a argument over bills. His checks have been short for three weeks now due to him just starting his job and not getting holiday pay.

He blames it on me. I had the money for two of the bills in my wallet but he had to get half of it bc he need some work stuff. I understood that and was not upset but trying to figure out a solution to our problem. he just keeps yelling at me and punching stuff. I'm all upset that I'm cramping really bad and I told him that I'm hurting and he said he didn't care that I have to many problems anyway. He says I don't contribute in any way that I should just shut up. I'm a sahm of our other two children. Idk what I did to deserve to be treated like this.
