Seeing baby move but not feeling him

stella

I’m 23+4 and I haven’t felt my baby move in a way that I know for sure it’s him moving but I can sometimes see or feel my stomach get hard or stick out for some time then go back to normal. Is it normal to not feel movement from the inside but can feel movement from the outside?

For example I won’t feel him move to a certain position but my stomach will get hard in a certain area for a bit then go back to normal
