Aw, normal yan mommy! 30 weeks pa lang kasi, and every pregnancy talaga is different, some mommies show early, some show later, so don't worry if your tummy looks smaller compared sa iba. A few of us moms actually had low bumps din throughout, at perfectly healthy naman ang babies namin sa end! But para sure lang and to get peace of mind, best i-mention mo sa OB mo sa next checkup para ma-monitor lang niya properly, lalo na kung worried ka talaga.
