What symptom would typically not indicate a normal pregnancy?

Facial edema is not considered a typical or normal symptom of pregnancy. While it is common for pregnant individuals to experience some degree of swelling—particularly in the legs and feet due to fluid retention—facial edema can be a sign of underlying issues, such as preeclampsia or other forms of hypertension. These conditions are characterized by elevated blood pressure and can pose serious risks to the health of both the mother and the fetus.

Increased heart rate occurs as the body adapts to pregnancy, accommodating the heightened blood volume and metabolic demands. Chadwick's sign, which is the bluish discoloration of the cervix and vaginal walls due to increased blood flow, is a well-established early sign of pregnancy. Similarly, increased blood volume is a normal physiological change during pregnancy, supporting the growing fetus and preparing for delivery. An understanding of these typical physiological changes is crucial for differentiating between normal pregnancy symptoms and potential complications.
