Ultrasound every week

Hi mga momsh, yung OB ko kasi walang sariling ultrasound since shared clinic yun with other doctors. I’m 24 weeks and 5 days today but ask ko lang lalo na sa hindi na first time moms if okay lang ba magpa ultrasound ako every week sa 8th month ko soon, natatakot kasi kami sa possibility ng cord coil. Thank you 😊
