Red scratch marks help

Jess • Been with the love of my love for almost 8 years, married 17/08/19 baby boy 💙 👶 05/10/2019 baby boy 💙👶 April 2022 baby girl 🩷🧒 March 2024

I’m 36 weeks now over the last couple days I’ve noticed this red scratch like mark that appeared on my stomach they started as just a small mark now it’s stretched out. Has anyone had this before?
