Im 13 wks pregnant. My half sister who doesn't live here no more came to pick up half her shit . She kept calling me a a bitch and i told her to grab her shit and leave. She started hitting me in the face made my nose bleed and dropped me on the floor and continued to hit me in the face . All this happend yesterday. Can i still file a police report today against her ?! I have a big bruise besides my eye and my nose is swollen. Or shouldi have called the cops yesterday ?!
