Is a low-lying placenta at 13 weeks of pregnancy common?

In general, a low-lying placenta at 13 weeks of pregnancy is a relatively common phenomenon clinically. If there are no abnormal symptoms such as vaginal bleeding or abdominal pain, it may be considered normal. Detailed analysis is as follows:

At 13 weeks of pregnancy, it is common for the placenta in some pregnant women to be located in the lower segment of the uterus, near the cervix. This is because as the pregnancy progresses, the uterus gradually enlarges and the placenta usually moves upward to a safer position. Therefore, finding a low-lying placenta in early pregnancy is not unusual, and in many cases, this condition improves naturally as the pregnancy advances.

If at 13 weeks the placenta completely covers the cervical opening or is very close to it, this condition is known as placenta previa, which requires medical attention. Placenta previa may increase the risk of bleeding during pregnancy, preterm birth, and placental abruption, posing threats to both maternal and fetal health. In such cases, sudden increases in physical activity or strenuous exercise are not recommended to reduce the risk of bleeding. Pregnant women should follow their doctor's instructions, may require regular monitoring of placental position, and should be prepared to seek medical care when necessary.

During pregnancy, maintaining a healthy lifestyle, resting in a lying position, getting plenty of rest, avoiding excessive fatigue and sexual activity may help reduce pressure on the placenta.
