Do Placenta Move During Pregnancy?

In most pregnancies the placenta attaches to the main part of the womb. But for some women, the placenta attaches lower down and may cover some or all of the cervix (entrance to the womb). In most cases of a low-lying placenta, the placenta moves upwards and out of the way as the uterus grows during pregnancy.

In which week placenta moves up?

They're usually spotted on your routine 20-week ultrasound. As the uterus grows upwards, the placenta is likely to move away from the cervix. Your midwife will check for this during an extra scan at 32 weeks (RCOG, 2018a).

Can placenta move from anterior to posterior?

It is very common for the position of the placenta to change as the uterus stretches and grows. An anterior placenta can migrate toward the top, sides, or back of the uterus as the weeks go on.
