Changes to Movement Pattern ni Baby

Hi mommies. Not sure if ako lang. Napansin ko kasi since yesterday na nagbago ung pattern ng movement ni baby. Ung usual time na dapat magalaw sya hndi sya ganun ka active pero gumagalaw nmn.. Also, parang humina ung mga kicks nya. May times na malakas pero hndi sya consistent unlike before. I'm doing yung fetal kick counts and so far nkaka-10 kicks and galaw nmn sya every hour. Nba-bother ako kasi hndi ako nasanay. Meron ba ko dapat na ika-worry? 30 weeks pregnant here.
