The earliest symptom of early pregnancy is menopause or abnormal menstruation. Pregnancy is highly suspected if the menstruation is delayed for more than 10 days, along with pregnancy may appear symptoms such as chilliness, dizziness, salivation, weakness, drowsiness, lack of appetite, nausea, morning vomiting, preference for acidic food and emotional changes, which can be diagnosed by early pregnancy test paper or checking blood HCG. After the delay of menstruation, keep your mood relaxed, get enough sleep, eat a balanced diet with three meals, eat warm fruits appropriately, prohibit strenuous exercise and medication, and be prepared for pregnancy. If pregnancy is confirmed, pay attention to abdominal pain and vaginal bleeding. It is recommended to go to hospital for examination around 45 days after menopause to determine whether it is intrauterine pregnancy, whether there is fetal heart and fetal bud, and to exclude ectopic pregnancy.
