Toddler fell on my stomach- how to know if it is serious

so

Im not pregnant, but two days in a row my toddler has landed somewhere on my stomach area, really hard. It was so painful, I yelled and sweared twice. The second time he was walking above me and then just straight sat on me from a height. Im just worried if my organs and everything will be okay? No vomiting or crazy symptoms, or even much pain in the areas, just some soreness. Also, i dont have health insurance
