Got jumped at 36 weeks...

Please no judging. I was out walking the track and a group of girls started talking tp me and one came from behins me and pulled me to thw ground by my hair and the pther girls jumped on me and startes hitting me. I have never met or seen these girls before, i have no clue who they are. Im only 17 and they looked about 25ish. One of the girls punched my stomach a few times but i was trying to cover it up with my knees and arms so atleast my belly was safe.. I ended up still getting hit in the stomach, getting kicked in the side and in the face and all that, and my stomach is so sore just to the touch.. I got home and took a shower and just washint my body, it hurt to even slide my hand over my belly. My baby is still movinf a lot, but when he moves my stomach just hurts soo bad.. I dont know exactly what to do, because baby is moving but my stomach just hurts so bad like sore.. I looked up alot on line and everything said my baby is very well protected but im so stressed out and worried and confused on why me and just feel so alone. Some one please give me sone kind of advice...
