Please help me

So my boyfriend and I just got into a major fight. Like huge to where it go physical. I slapped him and he slapped me back. He climbed on me, put weight on my arms with his legs, it got really violent. But... I'm 14/2 pregnant. He never touched my stomach except for almost sitting on it. Except I'm starting to feel cramps. My dog has pounced pretty hard on my stomach before and things have been ok. I have felt the little flutters and bubbles. So far it's cramping like when I first got pregnant. It's really low, lower than my pubic hair line. I think I still feel the flutters, but the cramping is on and off. I was wondering what that could be? Should I go to the doctor? Or will I be ok? I'm really scared. My baby may be young but it's all I care about. I don't wanna lose my jelly bean. 😔 please help me.
