Oo normal yan, mamsh! At 38 weeks that's usually your mucus plug or increased discharge as your body prepares for labor, it's actually a sign na malapit na, which is good. A few of us pregnant friends noticed the same thing and ang OB namin lahat said it's fine as long as walang foul smell or bleeding, but since you're already at 38 weeks, best check with your doctor lang para ma-confirm everything's on track at walang infection.
