Aw yan na yan, quickening! At 21 weeks ka na kaya definitely yan na yung feeling ng baby moving, parang may bubbles or light fluttering muna tapos magiging mas strong na siya as the weeks go by. A few of us mums noticed it parang gas o butterflies lang at first, tapos nag-panic kami na baka normal lang, pero super normal yon, lalo na kung second pregnancy mo kasi nakikita mo agad ang signs! Enjoy mo na yan habang mas light pa lang, kasi when they get bigger talaga mapapakita na sa outside yung kicks mo haha, very cool na moment yan, trust me!
