Yup, normal yan! Around 4 months kasi parang mas nagiging active ang baby, so ang pitik-pitik mo feeling ay ang movements niya na lumalaki, honestly a few of us moms felt the same thing at that stage, parang flutter or bubble popping sensation. Basta consistent siya and nagpapasaya ka, okay lang yan, pero if you're worried or parang may changes sa pattern, best talaga pag-usapan mo with your OB during your next check-up para peace of mind mo. Congrats sa buntis!
