The symptoms of early pregnancy mainly include menopause, early pregnancy reaction, frequent urination and breast changes. The early and late appearance and severity of symptoms vary among pregnant women with different body types, and the common symptoms are as follows: 1. Menopause: It is the earliest symptom of first pregnancy. For women of childbearing age with normal sexual life, if they have regular menstruation, they should be highly suspicious of pregnancy once their periods are over. 2.Early pregnancy reaction: Early pregnancy reaction can occur after pregnancy due to the change of hormone level in women’s body, such as coldness, dizziness, weakness of limbs, drowsiness, nausea and vomiting, dislike of greasy and sour food, etc. It appears around 6 weeks after menopause and disappears on its own around 12 weeks. The reaction can be light or heavy due to the different physical qualities of individuals. The lighter ones can be relieved after paying attention to diet and rest; the heavier ones need to be hospitalized for rehydration and adjustment. 3. Frequent urination: In the early stage of pregnancy, the enlarged uterus presses the bladder in front of the pelvic cavity, causing the pregnant mother to have the urge to urinate, so she urinates frequently. As the pregnancy lengthens, the enlarged uterus gradually enters the abdominal cavity and the symptoms of frequent urination gradually disappear. 4, breast changes: pregnant mothers can feel breast swelling and pain, breast volume gradually becomes larger, nipple areola increases, coloring deepens, dark brown nodules may appear around the areola. The early stage of pregnancy is a critical period for the development of the fetus. When women of childbearing age who have normal sexual life find that their menstruation is delayed or the above-mentioned related symptoms, they need to clarify whether they are pregnant in time.
