I was kicked twice in my stomach

I work with high schoolers with emotion and behavior issues. Yesterday a 17 year old male student had an episode where he attacked two fellow students and I. I tried my best to defuse the situation but nothing works when he's in attack mode. Consequently I was kicked twice in my stomach by the student with a shoe size of 12 or 13! I filled out an incident report and went to the Hospital. After 4 hours of being monitored baby is doing great. I realize the students I work with have issues but I'm feeling like I need to return to work after my baby is born...I just don't want to risk it happening again. Any suggestions ? What would you do?
