So far no stretchmarks... yet. My mom didn't get any with her first, but with me and my brother (twins) she said she got a lot, but I guess that can be expected. My sister has some too, so if it's genetic, looks like I can expect them. Also, many women I have spoken to about it say that even if I am lucky so far, the last month is when they will probably appear. Guess I'll just have to wait and see.
