Bulging stretch marks?

AnneMarie

So laying down tonight I felt one of my stretch marks bulging. Everything I've found said this can be normal and it will go away after baby is born. It wasn't bulging earlier today. I am 31 weeks pregnant today and had a high risk abnormal pregnancy with my girls so everything is new to me at this stage as I was inpatient with the girls at 24+5 and delivered at 32. It's not painful. Has anyone experienced this? What was the outcome?
