- After menstruation: Small amount, thick, often cloudy or sticky.
- Before ovulation: Increasingly clear, stretchy (like egg white) and spinnable – optimal for sperm.
- After ovulation: Viscous and opaque again.
Function: It protects the uterus from germs , supports or inhibits (depending on the phase) the advance of sperm and helps with natural cycle monitoring (e.g. with the symptothermal method ).

1. Cervical mucus tells you when you are fertile
Cervical mucus is an essential indicator for determining your fertile days . The mucus changes throughout your cycle and shows you exactly when you are fertile. To identify the best time for conception or for natural family planning, it's helpful to be able to correctly interpret the different types of mucus . During the fertile phase, for example, cervical mucus is clear and stretchy – a signal that ovulation is imminent.

2. The different phases of cervical mucus
Cervical mucus changes from cycle to cycle and even within a cycle . It goes through different phases: from cloudy and thick to clear and stretchy , and this tells you how close you are to ovulation . By observing your cervical mucus daily, you can pinpoint exactly when you are most fertile.

3. Cervical mucus as a natural method of contraception
For those who rely on hormone-free contraception , cervical mucus is a valuable indicator . Combined with other bodily symptoms , it makes it easy to determine your fertile window – completely without the pill, IUD, or other artificial contraceptive methods.
