As soon as that EPT test shows up red, your girlfriends gather with reams of advice: Ginger for morning sickness, Maalox for heartburn, bags of frozen vegetables for swollen ankles. As for stretch marks? There's no scientific prevention, but that doesn't stop our girlfriends from offering up remedies. We're particularly fond of one concoction, passed along by a girlfriend who earned her college tuition behind the counter at Lotions and Potions, one of the Valley's first bath and body shops. She suggested a four-ounce bottle of Lotions and Potions massage oil, mixed with a quarter-ounce of Vitamin E oil. Top it off with your choice from the shop's wide assortment of scents -- everything from strawberry to sandalwood. We can't guarantee it'll prevent stretch marks, but it sure feels great. And as any pregnant woman can tell you, that's a premium worth not passing up.
