Clicking sound??

This may sound extremely odd but I’m 30 weeks and depending on the position I’m laying or sitting in, when my baby kicks it makes a clicking sound.

I’ve just started noticing it this week since my belly is so big and tight that it hurts.

Today I was hunched over the table on my laptop and when he kicked a couple times it made this weird clicking sound and feeling. Almost like your knee clicking/ cracking when you pop a squat lol. Doesn’t hurt I just wanna know what it is.

Am I weird? Is this normal? What is it?
