Introduction
In early pregnancy, a low-lying placenta usually moves upward by around four weeks. A low-lying placenta mainly refers to a situation detected by color ultrasound before 28 weeks of gestation, where the lower edge of the placenta is less than three centimeters from the cervical os or covers the internal cervical opening. Causes of a low-lying placenta include uterine abnormalities, unhealthy lifestyle habits such as smoking and drinking alcohol, previous cesarean sections, and repeated abortions, all of which may contribute to this condition.

When a low-lying placenta is detected early, it typically moves upward within about four weeks, as the uterus significantly enlarges during this period and the placenta gradually migrates upward. If checked too soon, the uterus will not have changed noticeably and the placenta may not yet appear to have moved. During this time, pregnant women should avoid activities such as squatting or bending over, as these movements may pull on the placenta and lead to bleeding.
During early pregnancy, it's important to get plenty of bed rest, avoid large movements or strenuous exercise to prevent miscarriage, and consume more fresh fruits and vegetables rich in vitamins.
