Fetus on the right side in late pregnancy may be a normal reaction or embryo hypoxia, which should be analyzed in conjunction with the frequency of fetal movement. 1. Normal reaction: under normal circumstances in late pregnancy, the fetus may be on the lower left side of the abdomen, or on the lower right side of the abdomen, as long as the head of the fetus is facing downward in late pregnancy, and the fetal movement is regular, generally no special treatment. 2. Embryonic hypoxia: if the fetus is always on the right side in late pregnancy and the frequency of fetal movement is relatively high, it should be considered that intrauterine hypoxia is occurring, which is usually related to the scarcity of amniotic fluid or compression. If you find that the fetus is always on the right side, you can go to the hospital for a pregnancy test to understand the development of the embryo, if the embryo development is not affected, there is no need to worry too much, and there is no need for special treatment, regular observation can be.
