Patient's question:
At 18 weeks of pregnancy, the ultrasound showed that the placenta was located on the posterior wall of the uterus, with its lower margin close to the internal cervical os.Doctor's answer:
Your low fetal position usually doesn't need to be a concern, but if the placenta's lower edge reaches the internal cervical os, it indicates placenta previa. In such cases, if there are no significant changes later on, it's important to be vigilant about bleeding during pregnancy, especially in the third trimester when there's a risk of bleeding and preterm labor. Avoid sexual activity during pregnancy.
