Cervical mucus plays a fundamental role in the TTC process by nourishing and protecting sperm as it makes the long, arduous journey through the female reproductive tract to meet the egg. So, as you become more familiar with your cervical mucus, you will be able to better time having sex in order to conceive. In simple terms, cervical mucus is a fluid secreted by the cervix, theproduction of which is stimulated by the hormone estrogen. Throughout your menstrual cycle, the amount and quality of cervical mucus that is produced will fluctuate, and by observing these changes you can begin to predict the most fertile days in your cycle.
As you approach ovulation, your estrogen levels begin to surge, which causes your cervix to secrete more cervical mucus that is of a so-called “fertile quality”. This fertile-quality cervical mucus, also known as egg white cervical mucus (EWCM), is clear and stretchy, similar to the consistency of egg whites, and is the perfect protective medium for sperm in terms of texture and ph. Having enough egg white cervical mucus during your fertile window will actually improve your chances of conceiving. And, by noticing when your body is producing egg white cervical mucus, you will be able to identify your most fertile days.
The most accurate way to identify changes in your cervical mucus is to collect and observe a sample of mucus on a daily basis. To do this, wash and dry your hands well, then insert your middle or index finger into your vagina, getting as close to your cervix as possible.
