Does having egg-white cervical mucus (EWCM) mean that I am fertile?

Egg white cervical mucus (EWCM) is a type of cervical fluid that is produced right before ovulation, during a time when you are most fertile. This mucus is called EWCM because it strongly resembles raw egg white in that it is clear or streaked, and is very stretchy and can also be watery. By placing your clean fingers into your vagina and obtaining a sample you can check for the appearance of EWCM. When a sample of mucus is between your fingers, it may stretch for several inches and should like somewhat like raw egg whites.

EWCM usually indicates fertility and that you are close to ovulation.

Women in their early twenties typically have more days of EWCM than women in their thirties. Although it is not always true, women in their twenties will have around 5 days of EWCM and women in their thirties may have only 1 or two days with EWCM. Being that this mucus is necessary for conception, you should try to increase the amount you have present. This can be done by preventing dehydration and using supplements like evening primrose oil. FertileCM is a safe, dietary supplement formulated specifically to help increase EWCM quantity and quality.

What is cervical mucus?

The physical properties of the cervical mucus change during the menstrual cycle. The cervical mucus is produced by the cervix and changes consistency throughout your menstrual cycle based on hormones associated with fertility, egg development, and ovulation. Shortly after the menstrual period ends, the cervical mucus is dry and prevents sperm from penetrating the cervix but around the time of ovulation it becomes thin, has egg-white consistency, and is penetrable by sperm.

Cervical mucus (CM) is produced by glands in the cervix, the entrance to the uterus. It accepts, filters, prepares, and releases sperm for successful transport to the inside of the uterus, then, on to the fallopian tubes and the egg for fertilization.

How does cervical mucus change?

Cervical mucus changes are common throughout the natural menstrual cycle that women experience each month. For women who are trying to conceive, the changes in cervical mucus can play a factor in choosing just the right time for trying to get pregnant. About a week before ovulation, under the influence of estrogen, cervical mucus becomes abundant, sticky, and thick. 

Cervical Mucus Throughout the Menstrual Cycle 

Day in cycle (approximate) Consistency 
Days 1-5  Menses; menstrual period; bleeding
Days 6-9  Dry; little or no cervical mucus 
Days 10-12  Sticky thick mucus, becoming less thick and whiter 
Days 13-15 (most fertile time)  Egg-white or "spinnbarkeit" mucus: thin, elastic, slippery; stretchy, clear 
Days 16-21   Sticky thick cervical mucus
Days 22-28  Dry cervical mucus


What happens to cervical mucus during pregnancy?

Making the diagnosis of pregnancy solely from changes in the cervical mucus is too unreliable. You cannot make a pregnancy diagnosis from cervical changes alone. The typical stretchy and fertile cervical mucus develops under the influence of estrogen hormones. Estrogen hormones rise just before ovulation and decrease just after ovulation. At that time, cervical mucus becomes dry. About 7-10 days after ovulation, estrogen hormones normally rise again, and it is this second rise than can often give the appearance of fertile mucus again. That doesn't mean you are fertile again because you don't ovulate again. There are no reliable enough changes of the cervical mucus to indicate when implantation or pregnancy has happened.

How does ejaculate affect cervical mucus?

Ejaculate may interfere with the cervical mucus consistency. Most of the ejaculate is usually absorbed from the vagina within hours after intercourse. Though there is sperm in the cervix even after that time, the sperm is unlikely to interfere with the cervical mucus consistency.

Do I have enough cervical mucus?

One of the major concerns of women who are trying to conceive is that they don't have enough cervical mucus. However, cervical mucus is rarely a reason for infertility. In less than 5% of infertile couples, there is a problem with the cervical mucus, while over 80% have a problem either with ovulation, sperm, or the fallopian tubes. If you think that you don't have enough cervical mucus, an underlying cause such as anovulation (no ovulation) may be responsible for this, and that cause must be treated first. Trying to improve the mucus when there are other problems won't work. You can also ask your doctor to check you at the time of ovulation to verify your observation. 

Taking over-the-counter and prescription medications can change the consistency of cervical mucus. Fertility drugs may also alter consistency, so reading cervical mucus in these situations may be more difficult or impossible.
