Sleeping half-lying in late pregnancy may or may not have an effect on the fetus.
Normally, when a pregnant woman is pregnant, amniotic fluid will be present in the uterine cavity, which can play a protective role, and in the case of half-lying posture, it will not cause greater pressure on the fetus, so there will not be too great an impact on the fetus, and there is no need to worry too much.
It should be noted that some pregnant women may be in the late stages of pregnancy, long-term in a half lying position, especially lying on the back, in this case, the uterus will compress the inferior vena cava, causing pregnant women low blood pressure, which in turn causes intrauterine ischemia and hypoxia of the fetus, and may even cause fetal death or premature birth phenomenon.
It is recommended that pregnant women in the late stages of pregnancy should avoid maintaining the same position for a long time, can be appropriate to change the position, but also to count the fetal movement, to prevent the fetus intrauterine hypoxia.
