In the early stage of pregnancy, since the embryo has just settled into the uterine cavity, it is not firm yet, so women should pay attention to proper rest, regular life, avoid getting cold and flu. If you are overworked, it may lead to the unstable level of hormones secreted by the ovaries and endocrine disorder, which cannot meet the needs of the early embryo growth and development, and it is easy to have a precursory miscarriage such as lower abdominal pain and a small amount of vaginal bleeding, and in serious cases, inevitable miscarriage may occur. When a woman is pregnant, she should pay attention to proper rest, not to overwork, and also to increase nutrition, especially the need for protein, vitamins and minerals, which can be supplemented by fish and shrimp, meat, milk, eggs, as well as vegetables and fruits, which are conducive to the growth and development of the fetus.
