What Do You Use To Prevent Stretch Marks?

I've always had stretch marks since I was a little girl and they've only increased since I've gained weight since college. However, I'm trying to prevent more from appearing during this pregnancy. Right now I'm using coconut oil but I'm open to trying different inexpensive brands. Has anyone had success with coconut oil? What do you use to prevent stretch marks?
