28 weeks

Hi po. Is it normal na mag decrease yung movement ni baby at 28 weeks. The past few weeks of my pregnancy, very active si baby, halos buong araw sya active. Pero ngayon may certain time na lang po sya kung gumalaw. Pinostpone po kasi ng OB ko yung check up, kung di naman daw po urgent yung matter continue na lang daw po yung meds. I dont know kung paranoid lang ako or what. ?
