Massive kick feeling but not baby

Ni

Im 14 weeks tomorrow, im sitting in the garden and i get what i can only describe as a massive kick feeling under my right rib. I know its not baby as he's the other side at the bottom. And he's to small. It felt like a full grown baby walloped me. Has anyone got any idea what the heck it was ? I jumped out my chair when it happened as i was shocked it happened lol
