Sudden movements

Hello mommies, first time mom here. Im 37 weeks and 4days, yet wala pa lumalabas saking "bloody show" pero madalas sumasakit puson ko. Saglit saglit lang. si baby naman, hindi na sya ganon kaactive kumilos pero madalas tumigas tyan ko at yung pintig lang nya nararamdaman ko. Normal po ba yon? Salamat #advicepls
