Hit in the stomach

I work in a school with special needs kids and today one of my students jumped backwards and her butt hit right into my stomach pretty hard. It definitely hurt when it happened. After having my hormonal emotional breakdown of tears in the bathroom I went back to class and went on with my day. Baby is definitely moving but I'm super worried that something could be wrong. Am I just overreacting and everything is okay? I'm not bleeding I'm not really in any pain. A little bit achy but nothing serious. Should I just monitor her movement and see how I feel tomorrow? If I feel any pains tomorrow then call the doctor? Anyone have any similar situations?
