Patient's question:
During pregnancy, it is always particularly uncomfortable, and morning sickness is also very severe. How far is the normal placenta from the cervix?Doctor's answer:
At 14 weeks of pregnancy, there is no exact number to determine how far the placenta should be from the internal cervical os to be considered normal, as the placenta can still move upward with the growth of the uterus at this stage. If ultrasound shows a low-lying placenta but it has not reached the cervical os and there are no symptoms such as vaginal bleeding, observation may be recommended. If the pregnancy reaches 28 weeks and the placenta has not moved up, it would be classified as placenta previa, which is considered a high-risk pregnancy. You should now pay attention to regular prenatal check-ups and seek medical attention promptly if you experience any discomfort.
