Haha yes mommy, totally normal yan! I remember feeling the same thing during my first pregnancy kaya super worried ako, pero kinita ko sa OB na baby lang talaga ang gumagalaw at sometimes ang movements nila talaga parang may gas or bubbles, lalo na pag active sila or pag kumain ka ng maraming pagkain. A few of us moms sa barkada namin din nag-share ng parang gargling or popping sensations namin, it's just part of pregnancy kaya don't worry, baby is just doing their thing in there!
