Aiyoh sayang, ni memang common during pregnancy, hormone changes kan buat kulit jadi sensitive and itchy gila gila! A few of my mum friends kena gini juga around 15-16 weeks, so you're not alone. Best thing is check with your gynae or dermatologist sebab they can recommend products yang safe for you and baby, especially since you're worried about scarring, maybe dia boleh suggest cream yang help fade those marks. In the meantime, stick to fragrance-free lotion (oatmeal-based ones are quite soothing), try to resist the urge to scratch (I know susah!), and make sure your maternity clothes aren't too tight or warm. Jangan stress ya, usually this settles down after first trimester once hormones stabilize!
