Pregnancy question: when babies kick is it normally in the same spot?

I’m 18 weeks pregnant and having a hard time trying to distinguish this, I think I just felt my baby kick from the outside for the first time, I’ve felt him kick me from on the inside before but I was just rubbing my tummy and felt a nice kick and bump against my hand but it could of been something else.. It was 3 bumps, About 2 minutes apart, 2 were in the same spot, and the last was about an inch away from the original bump, and now its just stopped, Does it sound like my baby?
