Aww, congrats sa 19 weeks! Hindi ka pa nag-feel ng sipa pero normal lang yan, usually around week 16-25 pa lang ang first movements, lalo na kung first time mo pa. When it comes, it feels like light flutter lang or parang may bubbles popping inside, kaya maraming first-time moms ang nag-miss ng initial kicks dahil akala nila gas lang or muscle twitch hehe. A few of us moms observed more pa when we were lying down or relaxed, plus mas magsisiguro ka na baby movement yun once it gets stronger, around 3-4 months pa lang ang full kicks na talagang distinct!
