Which sign may be indicative of pregnancy during a clinical examination?

Hegar's sign is an important clinical indicator of pregnancy. It is characterized by the softening of the lower uterine segment, which can typically be felt during a pelvic examination around six to eight weeks into the pregnancy. This sign reflects the hormonal changes and increased blood flow associated with early pregnancy, providing a reliable physical indication that a healthcare provider might look for during a clinical evaluation.

Chadwick's sign, while also an early sign of pregnancy, refers to the bluish discoloration of the cervix, vagina, and vulva due to increased vascularity and may typically appear around the same time as Hegar's sign. Montgomery's tubercles are sebaceous glands on the areola that become more prominent during pregnancy but are not a definitive sign of pregnancy when examined clinically. Godell's sign refers to the softening of the cervix and occurs later in pregnancy, making Hegar's sign a more specific early indicator.
