Which physical change is often noted early in pregnancy?

• A. Increased weight
• B. Frequent headaches
• C. Chadwick's sign
• D. Sensitive skin

Answer: (C)

Chadwick's sign is a notable physical change early in pregnancy, characterized by a bluish discoloration of the cervix, vagina, and labia. This change occurs due to increased blood flow to the pelvic area, which is a common physiological response during the early stages of pregnancy. It serves as a potential indicator of pregnancy for healthcare providers during examinations. This sign typically appears around the sixth week of gestation and can be one of the early observable signs of pregnancy.

In contrast, while increased weight, frequent headaches, and sensitive skin can be associated with pregnancy, they may not present as early or as reliably as Chadwick's sign. Increased weight is usually more evident later in pregnancy, frequent headaches can have various causes unrelated to pregnancy, and sensitive skin may arise due to hormonal changes, but not specifically indicate pregnancy as clearly as Chadwick's sign does.
