Aiyo, itchy and white discharge is super common during pregnancy, hormones kena gila-gila! Most of the time it's normal thrush (fungal infection) which happens to so many of us when we're expecting, the pH down there changes and gives fungi a good time to party lah. But since you're pregnant and it's bothering you, best to check with your gynae to confirm what it is and get the right treatment, okay? They can give you safe options for pregnancy, so don't tahan-tahan the discomfort.
