Totally normal yan, mommy! At 27 weeks, mas malakas na talaga ang movements kaya mas nararamdaman mo siya, especially around the belly area kung nasaan ang placenta mo at kung paano siya naka-position sa loob, a few of us moms noticed the same thing, na parang concentrated ang kicks sa isang spot lang. That "parang malalaglag" feeling is just the strong kicks at movements niya, pero if it makes you feel better or you're worried, worth mentioning sa OB mo during your next check-up para ma-ease your mind.
