Cervical mucus, also known as cervical fluid, is a natural and normal substance produced by the cervix. It plays a crucial role in a woman’s fertility as it helps to keep sperm alive and able to reach the egg for fertilization. The appearance and consistency of cervical mucus change throughout a woman’s menstrual cycle, and these changes can indicate fertility or infertility. In this blog post, we will discuss the different types of cervical mucus and what they indicate for fertility.
Type 1: Dry or Sticky Cervical Mucus
At the beginning and end of a woman’s menstrual cycle, her cervical mucus may be dry or sticky. This type of cervical mucus is not fertile as it makes it difficult for sperm to survive and reach the egg. It may also indicate that a woman is not in her fertile window and is unlikely to conceive during this time.
Type 2: Creamy Cervical Mucus
Creamy cervical mucus is a thick, white, and lotion-like discharge that is present in the days leading up to ovulation. It provides a nourishing environment for sperm and helps them to survive longer. This type of cervical mucus also indicates that a woman is approaching her fertile window and is more likely to conceive during this time.
Type 3: Watery Cervical Mucus
As a woman gets closer to ovulation, her cervical mucus may become watery and clear. This type of cervical mucus is highly fertile and helps sperm to swim more easily towards the egg. It also indicates that ovulation is imminent, and a woman is most fertile during this time.

The Different Types of Cervical Mucus and What They Indicate for Fertility
Type 4: Egg White Cervical Mucus
Egg white cervical mucus is the most fertile type of cervical mucus. It is clear, stretchy, and resembles raw egg whites. This type of cervical mucus indicates that a woman is at her peak fertility and is about to ovulate. It provides the ideal environment for sperm to reach and fertilize the egg.
Type 5: Sticky and Clumpy Cervical Mucus
After ovulation, a woman’s cervical mucus may become sticky and clumpy. This type of cervical mucus is not fertile and can make it difficult for sperm to survive. It also indicates that a woman’s fertile window has passed, and she is unlikely to conceive during this time.
Type 6: Brown or Pink Cervical Mucus
Brown or pink cervical mucus may appear towards the end of a woman’s menstrual cycle. It is an indication of old blood and is not a sign of fertility. However, if this type of cervical mucus is seen during the fertile window, it could be a sign of implantation and early pregnancy.
Type 7: Yellow or Green Cervical Mucus
Yellow or green cervical mucus is not normal and may indicate an infection. It is essential to consult a doctor if you experience this type of cervical mucus as it can affect fertility and overall reproductive health.
In summary, the appearance and consistency of cervical mucus can provide valuable information about a woman’s fertility. Dry or sticky cervical mucus indicates a low fertility window, while creamy and watery cervical mucus is more fertile. Egg white cervical mucus is the most fertile type, and sticky and clumpy cervical mucus is not fertile. Any abnormal colors or consistency in cervical mucus should be discussed with a doctor.
