Placenta tearing from uterus wall.

Last Friday I was tripped at work. I am 32weeks. Today I was ordered an altrasound. The results show that my placenta tearing from the uterus wall and showing that it had blood pocketing up. Basically told like a blood clot between it. I'm freaking out because basically if it continues to tear there could be serious complications. Has anyone else have this or have had this happened?
