Aiyoo mama, third trimester itching is the worst lah, I totally feel you! One of my mum friends swear by plain moisturiser like Cetaphil or even just coconut oil after shower while skin still damp, helps the scratching urge so much, plus you can use it safe-safe for baby later. But if it's really bad and you're scratching till bleeding, better check with your OB or midwife quick-quick, sebab sometimes it can be something like cholestasis yang need attention, so don't take chances k mama!
