Aww mama, normal lang yan sa 30 weeks, the hormones and the baby are doing their thing, kaya maraming discharge talaga ang mangyayari throughout pregnancy! A few of us moms experience different amounts at different times, so kung hindi itong greenish, foul-smelling, or may bleeding, you're likely okay lang. But since you're worried, best to mention it sa OB mo sa next check-up para ma-check lang properly, okay? Take care, mama!
