Pain when baby moves?

I'm 18 weeks pregnant with my second baby. I've been able to feel them move very clearly from very early on, I can tell what position they're in and everything.

For the past 2 days whenever they move I get very slight pain in the area where they push on my belly. It's clearly not a cramp or contraction or anything like that, just a slight sharp pain in one very small area on my belly.

I never had this with my first baby and was wondering if it was normal. Obviously it doesn't seem super concerning but I can't find anything about it online.

Anyone else getting this?
