Help...

So this happened I was going into the living room to grab my blank because my boyfriend had took our comforter. We were fighting because I found out he had a tinder. Oh by the way I’m 29 weeks pregnant. As I reached for it he pushed me and natural reaction I pushed him back. Then he really pushed me and I landed across the room. After that this is what he says. Am I wrong. I don’t know what to do from here.
