Definition

Noun: - A clinical sign of early pregnancy: A purplish or bluish discoloration observed on the mucous membrane of the vagina and cervix. This sign is considered an indicator of increased vascularity and blood flow to the pelvic region in the early stages of pregnancy.

Usage

• This term is used exclusively in a medical or clinical context, specifically within obstetrics and gynecology.

Examples

Advanced Usage

Notes
