Bending over in early pregnancy or for a short period of time in late pregnancy will not squeeze the fetus, but if you bend over for a long period of time, you will squeeze the fetus. At the beginning of pregnancy, because the fetus has just begun to develop, the volume in the uterus is relatively small, the uterus has not increased significantly, pregnant women bending over generally will not squeeze the fetus. In the middle and late pregnancy, the fetus gradually increase in size, accounting for the entire abdomen, pregnant women occasionally bend over for a short period of time due to the fetus in the uterine cavity with amniotic fluid and uterine wall, abdominal wall protection, will not extrude and affect the fetus. However, if bending over for a long time will squeeze the enlarged abdomen and compress the fetus, and will affect the blood circulation, which may lead to fetal restlessness in the uterine cavity or fetal hypoxia and other situations. It is recommended that pregnant women try to avoid prolonged bending in the middle and late stages of pregnancy to avoid causing back pain and discomfort or compression affecting the development of the fetus.
