Toddler fell on belly

My almost 3 year old just fell on my belly and it was kind of hard. He was jumping around and fell with his hands on my belly and I’m worried. My doctor told me “trauma” for the belly would be my son jumping on it and I feel like it was similar. Anyone else had any experiences like this? I’m going to look for bleeding and cramping but I’m freaking out a little bit. I know they are cushioned in there but it was just so hard and with his full weight idk!
