Does minimal cm mean the egg was fertilized already or not very fertile cm?

Minimal cervical mucus (CM) does not necessarily indicate whether an egg has been fertilized or not. CM is produced by the cervix and its consistency and amount can vary throughout the menstrual cycle. It can be an indicator of fertility, but it is not a definitive sign of ovulation or fertilization.

During the fertile window, which typically occurs around the middle of the menstrual cycle, estrogen levels rise, causing an increase in CM production. This CM is usually clear, stretchy, and slippery, resembling raw egg white. This type of CM is often referred to as fertile CM or ovulation CM. It helps sperm travel through the cervix and reach the uterus.

After ovulation, progesterone levels rise, leading to a decrease in CM production. The CM may become thicker, stickier, or even disappear. This type of CM is not conducive to sperm survival and is often referred to as infertile CM.

Therefore, minimal CM does not directly indicate whether an egg has been fertilized. If you are trying to conceive, it is essential to consider other factors such as your menstrual cycle, basal body temperature, and ovulation predictor kits to accurately determine your fertile window and increase your chances of conception.
