The first month of pregnancy is the stage when the fertilized egg has just been laid in the uterine cavity. At this time, the placenta is not yet developed, and once some instability occurs, the embryo will separate from the endometrium, thus producing the phenomenon of miscarriage. So this stage should pay extra attention to the body of pregnant women, mainly in the following areas: first, to ensure adequate sleep time, good rest to ensure a good physical condition. Second, pay attention to not strenuous exercise, the fetus is just laid very easy to detach from the uterine cavity, if the exercise is too strenuous will cause miscarriage. Thirdly, emotions should be kept stable, if something happens that causes an emotional breakdown, or too much excitement can easily lead to miscarriage.

Fifth, pay attention to pregnancy reactions, adapt and adjust to various discomforts in time. Pay attention to supplemental nutrition, eat more mild vegetables, fruits and high-quality protein food.
