If the placenta is in a low position, there may be a risk of preterm labor. It is recommended that only light activities such as lying down and walking are done at this time, and more exercise is not recommended. A low placenta is considered to be hypoplastic before 28 weeks and placenta previa after 28 weeks. When this happens, the placenta is prone to abruption, which can lead to abnormal vaginal bleeding when the baby is not full term. To avoid this, it is important to avoid excessive exercise, and it is recommended that the pregnant woman lie down as much as possible, and if necessary, walk slowly. If the placenta position is low, it is recommended to consult a doctor in time, take reasonable methods to intervene under the guidance of the doctor, and listen to the doctor’s arrangement, to prevent the occurrence of preterm labor and other situations, which will affect the health of the child.
