The current medical level has no way to determine the direction of the placenta growth, whether the placenta can grow up or not depends on the pregnancy week of the pregnant woman. Before 28 weeks of pregnancy, the placenta may grow up, but after 28 weeks of pregnancy, it is very unlikely to grow up. Generally before 28 weeks, if the placenta is found to be low in the ultrasound examination, with the increase of pregnancy week, the uterus will gradually increase in size, the lower part of the uterus will be elongated, and the placenta will be gradually drawn upwards and may become a normal position. After 28 weeks, especially after 32 weeks of gestation, if the ultrasound shows that the placenta position is still low, it is very unlikely that the placenta will move upward at this stage, and it will usually form a true placenta praevia or low placenta, and the pregnancy should be prolonged as long as possible to improve the fetal survival rate. During pregnancy, if a pregnant woman is found to have a low placenta, she should avoid excessive physical labor, avoid squatting, and should forbid intercourse to avoid bleeding. Pay attention to a balanced diet, avoid eating cold, spicy and stimulating foods, and maintain good laxative habits to avoid constipation. Pay attention to vulva cleanliness and hygiene, wear loose underwear, do not wear tight clothes, and go to the hospital regularly for pregnancy checkups. If there is vaginal bleeding or abdominal pain, you should consult a doctor in time to avoid danger.
