As a woman, your body is a walking biological computer that contains the most enlightening information about your fertility. Observation and charting of these fertility signs may be used to tell us details regarding our cycles.

Tracking Signs of Fertility will help increase your chance of a natural conception.

You may not realize unless you are charting that there is a distinct pattern of cervical fluid throughout your cycle.

What is it?

Cervical fluid is an important fertility sign, as it allows for the detection of the beginning of the fertile window. Throughout your menstrual cycle, the amount and quality of cervical fluid that is produced will fluctuate. By observing these changes you may predict the most fertile days in your cycle. The production of cervical fluid is initiated by the hormone estrogen, and is secreted by the cervix. As you approach ovulation, estrogen levels begin to surge, causing your cervix to secrete fertile quality cervical fluid.

What to look for

The easiest and most reliable way to check cervical fluid is to gather some with your fingers and then pay attention to the way it feels when you rub it between your fingers. Fertile cervical fluid is described as very slippery and wet, like raw egg white. It often causes extremely lubricative feeling at the vaginal opening. It may stretch several inches and when wiping with tissue, cervical fluid may feel slippery, lubricative or gliding.

Why do we have cervical fluid?

Cervical fluid has a primary role in assisting the sperm travel to the egg for conception. Sperm require a medium in which to live, move and thrive – otherwise they will quickly die. It is a substance that is necessary for sperm nourishment and mobility. Once the sperm travel from the penis to the vagina, they need an analogous substance to sustain them.

1. Protection

Provides an alkaline medium to protect the sperm from the otherwise acidic vagina

2. Nourishment

Nourishes the sperm

3. Filtration

Acts as a filtering mechanism

4. Transportation

Serves as a medium in which the sperm can move

Why is it important when trying to conceive?

Timed sexual intercourse with ovulation will increase your odds of achieving pregnancy! Cervical fluid is an important indicator for couples who are trying to conceive (TTC). As there is only one time each month that ovulation occurs, we can listen to what our bodies are telling us leading up to that moment, and time intercourse appropriately. When the estrogen in your body increases, you begin to produce cervical fluid as you prepare to ovulate a few days later.

Therefore, the presence of an egg white like cervical fluid is an enlightening indication from our bodies that ovulation is coming up.

Here's a tip:

Practically speaking, if you see egg white on Monday and take advantage of it by having intercourse that day-great! But, if you still see egg white the following Wednesday, have intercourse again because the ovum has probably not yet been released, and you are still extremely fertile. Tuesday would have also been a good day to try!

Using multiple fertility signs to predict your optimal time for conception is recommended. Other methods include: Taking your Waking Temperature, Position of Cervix and Ovulation Predictor Kits.
