Can there be a drastic change in the placental positions when the scan is taken at different centers?

Question

Hello doctor,

I took an anomaly scan in week 20. I got a low-lying anterior placenta and was 3.5 cm away from internal OS. After ten days; I took another ultrasound showing a low-lying placenta just reaching internal OS and was grade 2. Both scans were taken at different scan centers. I heard the placenta usually moves up, but it has moved down. What could be the reason for this drastic change in the placenta position?

Kindly suggest.

Hello,

Welcome to icliniq.com.

Thank you for trusting us with your health care.

I have gone through your history and understand your concerns.

Usually, the placenta is low-lying in early pregnancy and returns to normal after 28 weeks. There are many causes for the low-lying placenta. I think this difference in placenta position is due to the difference in scan center because such changes do not happen in just ten days.

You should not worry much about it. I suggest you rest properly, keep a pillow below your legs and repeat your ultrasound after 28 weeks.

Hope you found this useful. Feel free to ask for more information.

Good luck.

Regards.
