Aah common jugak ni during pregnancy! Kulit kita jadi more sensitive sebab hormone changes, plus maybe kulit jadi drier ke or lebih oily dari biasa, a few of my mum friends complained about this around second trimester. Dah try guna gentle facial cleanser and moisturiser? Apa product you're using sekarang? Kalo terus gatal or ada rash keluar, better check with your doctor or midwife la to rule out anything else, but in the meantime maybe switch to something gentle and fragrance-free untuk see if it helps.
