Cord coil (WORRIED)

Hi mommies! Sino po naka-experience ng single loose cord coil during pregnancy? I'm almost 32 weeks na po and kanina nagpa 3D/4D Ultrasound kami and dun nakita yung case ni baby. I was advised to drink 3 to 4 liters of water tapos repeat ultrasound kami on wednesday kasi tumalikod din si baby during the test. Who experienced the same thing po? Share nyo naman po experience nyo. Please pray for my baby na rin po. Thank you! ???
