anyone else experience this early on?

I’m 18w+3 and very active baby? I’m still quite small but, I was already able see kicks and pokes from the outside i think just around 17wks (not sure) and even a little before, I was be able to see my lil one buldging out to my right side very often but never my left side 🤔

but anyways this is my first pregnancy so just wondering, how big is the baby by 18 weeks & is being very active a good sign of a heathy baby?
