I'd say so, Stephy!
Personal question...do you use soap on your breasts? Soap dries skin out, so the more you use, the drier your skin will be, increasing itchiness and the chances of stretch marks. You can try using lansinoh already, or some other lotion to help soothe the itch. Otherwise, having been around the block a few times and had it recommended to me (and avoided stretch marks through 4 pregnancies), use soap only once a week. Your stomach and breasts aren't as dirty as the rest of your body gets, so it's perfectly safe to cut back on soap use on these areas to cut back on itching and stretch marks.
Think I've popped a bit too. 24 weeks vs 28 weeks. At 25 weeks, my uterus measured right on for dates and yesterday, I'm measuring at 31 weeks (28 weeks now)
