What charges can be brought about for a pregnant woman starting a physical fight?

With what could you charge a woman for starting a physical fight when she is pregnant? I was sitting in my car and a woman who is pregnant and doesn't like me came up to me and started yelling at me. I calmly asked her to leave me alone and that by law, I have all rights to be parked by my friend’s house, but that just seemed to make her even more angry. Then she reaches into my window and starts hitting me. I pushed her hands away and her boyfriend spit on me. She is probably about 6 or 7 months pregnant. What kind of legal action or charges can I press on this women?
