I'm 34 weeks, and am huge. So far I've escaped without stretchmarks apart from a few either side of the bump at my hips which didn't worry me too much. Today I noticed in the mirror that in the light I have lots and lots of stretchmarks about to appear (the skin is a different, more shiny, texture) and am feeling very upset about it! I had stretchmarks as a teenager on my hips and they were a horrible red-purple colour for years.
