Doctor's answer:
Normal placenta attaches to the bottom, posterior wall, anterior wall, or lateral wall of the uterine body. If the placenta attaches to the lower segment of the uterus, with its edge reaching or covering the internal cervical os and positioned lower than the fetal presenting part, it is called placenta previa. Whether the placenta is located on which wall is normal, but placenta previa is dangerous.
