Placenta abruptio; 3, parking pregnant women’s legs apart amplitude is relatively large, easy to stimulate the perineum, for some pregnant women with habitual abortion, easy to induce fetal movement or contractions. If the pregnant woman’s body is more flexible and the fetus is stable, she can consider riding an electric bicycle, but it is not recommended, especially the distance should not be too long, the speed should not be too fast, and at the same time need to ensure that the riding section of the road can not be too bumpy. It is best to reduce cycling in late pregnancy, when the abdomen is expanding and the body is not very flexible, prone to danger.
