Hi mama! White, thick discharge during pregnancy is super common, especially at your stage, it's your body's way of protecting baby na, kaya wag mag-alala masyado. But since you want to be sure it's nothing like an infection (yeast or bacterial), better check with your OB pang kasi hindi naman kami doctors, at they can do a quick swab if needed to rule out anything na kailangan i-treat.
