Egg White Cervical Mucus

Egg White Cervical Mucus (EWCM), a term often used in Fertility Awareness Methods, refers to the type of cervical mucus (CM) that is considered most beneficial to a woman's fertility. Named because of the CM's resemblance to raw egg white - wet, clearish, abundant, and very stretchy - particularly when compared to CM's consistency and amount on other days of the ovulatory cycle.

EWCM generally appears just before an egg cell has released from a woman's ovary (ovulation). Its purpose is to give sperm cells a smooth, quick journey to reach the waiting egg.
