Chadwick's sign
Introduction
Overview
Overview
Chadwick’s sign is a bluish discoloration of the cervix, vagina and vulva caused by venous congestion. It can be observed as early as 6-8 weeks after conception, and is often used as an early sign of pregnancy.
These color changes were discovered in approximately 1836 by French doctor Etienne Joseph Jacquemin (1796-1872).[1]
