Too early?

I was laying down and I started to feel my baby girl kick and move like crazy lol 😂 so I turned over and laid on my back and lifted my shirt. After a few seconds, she kicked so hard and I could see it from the outside. I was so confused but so happy and proud at the same time because I read that most ladies don't see their baby kick until 24 weeks or around that time. Does this mean that she's just strong or big? Haha or is it just me? I'm 19 weeks today btw. (Excuse the ratchetness 😂)
