CM (cervical mucus): What Is It, And Why Should I Check It?

Updated: Oct 25, 2021

What is Cervical Mucus?

Cervical mucus, also known as CM for short or Cervical fluid is a fluid produced by the cells of the cervix. Your Cervical mucus can tell you quite a lot more than you would think, for example, your mucus can help indicate infection, ovulation, and sometimes even early pregnancy.


Why check my Cervical Mucus?

Checking your cervical mucus can aid in fertility and conception by better helping you understand the timing of your cycle. Crevival mucus can help you predict when you are most fertile through detecting “peak” fertile mucus. This mucus best resembles raw Egg Whites with its snot-like consistency and stretch, earning it’s nickname, Egg White Cervical mucus or EWCM for short. ”Peak” fertile mucus is refer to your CM that provides the best environment for sperm and conception. The best time to try for conception is when this “peak” mucus is detected. The average female typically has EWCM for 1-2 days prior to ovulation, but this can be detected as early as 5 days prior to ovulation.

CM has also been known to be tracked and checked in the notorious TWW (two week wait), as in early pregnancy hormones cause CM to go into over-drive producing more CM than ever. However, all women are different, and the timing in which hormones raise vary across each woman and each subsequent pregnancy. The real tricky part is often many women have changes in their CM from cycle to cycle with never conceiving, and tracking your CM post ovulation to determine early pregnancy can be frustrating and upsetting. CM is NOT a reliable method of determining early pregnancy. But, some still believe early increased white watery and/or creamy CM after ovulation can be a sign of early pregnancy.

Cervical mucus can also be a great indicator of your vaginal health. No itch, No smell, No color, (usually) No Problem. If you do have one or more symptoms of itch, burning, foul or yeast-like smell or a color other than clear or white to your CM, see your physician.

The Cervical Mucus “Cycle”.

Cervical mucus changes throughout your cycle from period, to dry, to creamy, to wet/watery to stretchy/eggy (EWCM), to creamy/watery (second estrogen surge), to sticky and scant.
