Belly button piercing scar going to split?

Lauren • Had my sweet girl 02/22/20 - 5 weeks early due to rare genetic disorder💗 Had my handsome man 09/30/22 - 3 weeks early due to low birth weight💙

I had a scar above my belly button where my belly button piercing rejected in high school. Now that I’m pregnant (35 weeks) it keeps stretching and stretching and it now feels like it’s going to split the skin. It is so itchy and painful and gross looking.

Any advice on what I can do to help this?
