The fetal position of left occipitofront can be slept on the left side, and there is no clear relationship between the fetal position and the sleeping position of pregnant women. The left occipito-front position is one of the normal fetal positions and is also the easiest fetal position for delivery. The following points need to be noted about sleeping position in late pregnancy: 1. The left lateral position can be adopted in late pregnancy, which is beneficial to blood circulation and ensures the blood flow of the placenta, which is beneficial to the development of the fetus. However, pregnant women need to frequently turn around to avoid discomfort for a long time; 2, avoid long time right side lying and supine position, supine position is likely to cause postural hypotension, which is not good for the fetus and pregnant women; 3, late pregnancy is forbidden to sleep on their stomachs, which can cause premature birth and intrauterine distress and other unexpected situations. It is recommended that in the late pregnancy to check on time, try to check every two weeks after 30 weeks of pregnancy, and once a week after 36 weeks of pregnancy, pay attention to blood pressure, blood sugar, weight, and monitoring of uterine height, abdominal circumference, contractions, vaginal bleeding and other indicators. Pay attention to monitoring fetal movement in late pregnancy to avoid problems such as intrauterine hypoxia.
