Belly button sore as baby grows (had gall bladder surgery)

Victoria

I had my gall bladder out 11 years ago, and they went in through my belly button and a couple little spots on my belly (that have healed completely). But I’m 19 weeks pregnant and as my belly has started to grow I’ve been having pain in and right around my belly button, I assume from scar tissue. Has anyone else had this same experience? Is it going to get much worse? I guess there’s nothing to do about it, but I have this fear that like my belly button will rip or something.
