At this time, the development of the embryo is still unstable, so it is easy to be stimulated by the outside world and miscarriage occurs. In the early stages of pregnancy, you should pay attention to rest, avoid overexertion and prohibit intercourse. The development of the fetus needs sufficient nutrition, so you should eat more protein-rich foods, such as milk, lean meat, fish and eggs. At the same time, you should consume enough vegetables and fruits to maintain a balanced nutrition. If there is pain in the abdomen and vaginal bleeding, you should have a timely examination to avoid miscarriage. Folic acid should be supplemented in time for 10 days of pregnancy, which can help the development of fetal neural tube and prevent fetal malformation. You should also pay attention to your surroundings and avoid smoking, drinking alcohol, or exposure to chemicals and harmful radiation, etc. Pregnancy tests are very important and should be scheduled in advance.
