Reduced fetal movement

Anyone here who have experienced reduced fetal movement? Normal lang ba? I'm on my 37 + 4 weeks na. Usually sobrang active ng baby ko, pero ngayong araw minimal lang yung galaw niya, naninigas lang lagi yung tiyan ko. Kaka-ultrasound at check up ko lang nung 27, at ok naman daw siya. Nakakaparanoid lang kasi.
