Just to share with you an article on strecth mark that I found at http://pregnancy.baby-gaga.com/calendar/week22
And how's mom doing? Take a moment to think about this: your uterus has now stretched to such unholy proportions that it extends beyond your navel! The not-so-exciting part of this remarkable fact is that growth like this tends to leave stretch marks and can itch like nobody’s business. If you're genetically prone to get stretch marks (you are if you already have stretch marks elsewhere) it's unlikely you'll be able to completely prevent them during pregnancy.
Don’t get suckered into buying really expensive creams that supposedly make stretch marks ‘magically disappear.'Stretch marks are scars on your skin and won’t disappear with a topical cream .
But feel free to apply all the aloe-vera (and other anti-itch lotions) to alleviate the itching. In terms of preventing their appearance, cocoa butter-based creams and creams full of Vitamin E have a reputation for helping-- but there's still no guarantee that those pesky stretch marks won't show up despite your best creaming-up efforts.
