What are the symptoms of early pregnancy reactions?

Early pregnancy reactions are common physiological changes in women during the early stages of pregnancy, with various manifestations, primarily including the following: 1. **Amenorrhea (absence of menstruation):** For women of childbearing age with regular menstrual cycles, missed periods are the most obvious symptom of early pregnancy. 2. **Gastrointestinal reactions:** Such as nausea, vomiting, decreased appetite, and aversion to greasy foods. 3. **Breast changes:** The breasts may feel tender or tingly, the nipples may darken in color, and dark brown nodules may appear around the areola. 4. **Frequent urination:** Due to the gradually enlarging uterus pressing on the bladder, frequent urination may occur. 5. **Fatigue and drowsiness:** Some pregnant women may feel unusually tired, sleepy, and lack energy. 6. **Mood swings:** Due to hormonal changes and physical discomfort, pregnant women may become sensitive, irritable, or easily agitated. If you suspect you are pregnant, it is recommended to seek medical attention promptly for confirmation.
