Mine started at 7mo (30 weeks) and continued gradually until the end. I only got stretch marks in my first pregnancy, so hopefully I won't get any new ones this time either. My friends started somewhere around then as well, but didn't get awful until the last 2-3 weeks (her poor belly is wrecked). I have another friend that didn't get any until the last 2 days of pregnancy. Each person is so different..
Also, just cause you get stretch marks doesn't mean that your stomach won't go back. I have many around my hips and lower belly and my tummy has always looked pretty good within a year pp. You can see my belly photos from pregnancy #2 in the first post of this thread (there's a link).

When do most women typically START getting them? I haven't developed any new ones (at 20w6d w/ baby #1) - even on my boobs which have grown three full cup sizes since conception... And my belly is now much farther out than my boobs and I don't have any visible stretch marks yet, but my sister has them pretty bad from her first baby....










I know exactly what your talking about.
