May or may not be a dumb question

I'm 28 weeks and my stomach is starting to itch, which I know means my baby is growing and my skin is itching from being stretched. My question is if I scratch it, will it make my stretch marks worse or cause more stretch marks? Kinda feel stupid for asking this but I was just wondering.
