I lost a lot of weight before I got pregnant, so I haven't done a whole lot of stretching. I have old stretchmarks, so I wasn't too concerned about new ones, but I was starting to wonder if I'd escape them altogether. I finally noticed a few fresh ones at the bottom of my bump the other day - they're really sneaking in at the last minute! I'm really surprised I didn't get any on my breasts, they've been growing from the start and they were bigger than the biggest they've ever been months ago.
