The Cervical Mucus Method of NFP Made Simple




Introduction

The Cervical Mucus Method, a cornerstone of Natural Family Planning (NFP), empowers women to understand their fertility by observing changes in cervical mucus. This blog post aims to guide you through the method, helping you identify your fertile and infertile days.



What is Cervical Mucus?

  • Definition: Cervical mucus is a vaginal discharge produced by the cervix. Its texture and quantity change throughout the menstrual cycle due to hormonal fluctuations.

  • Role in Fertility: It protects sperm and aids their travel to the egg during the fertile window.


Understanding Cervical Mucus Changes

  • Before Ovulation: Estrogen levels rise, causing mucus to become more abundant, clear, stretchy, and lubricative (resembling raw egg whites...as seen in the picture above).

  • After Ovulation: Progesterone increases, making mucus thicker and less hospitable to sperm.


Tracking Your Cervical Mucus

  1. Observation: Check your cervical mucus daily. This can be done in the following steps:

    1. Wipe with flat toilet paper (folded not crumpled/bunched up) from front all the way back to the perineum (area between vagina and anus). Take note of if any lubricative sensation is present.

    2. Observe toilet paper for any cervical mucus.

    3. Use index finger to touch toilet paper to lift off any cervical mucus.

    4. Observe cervical mucus qualities (color and stretch) between thumb and index finger.

  2. Recording: Note the color, consistency, and feel of the mucus. Charting these observations can help identify patterns over time.

  3. Frequency of observations: Make observations before and after ever time you use the bathroom as well as before and after swimming or taking a shower/bath.


Identifying Fertility with Cervical Mucus

  • Fertile Window: When mucus is clear, stretchy, and slippery, it's likely you're in your fertile window.

  • Peak Day: This is the day of ovulation. This is the last day in which mucus will be observed having at least one of the three fertile signs (clear, stretchy, lubricative).

  • Infertile Times: When mucus is scant, thick, or absent, fertility is lower. This begins the first day after Peak Day, or the first day in which cervical mucus is neither clear, stretchy, nor lubricative.


Advantages of the Cervical Mucus Method

  • It's a natural, cost-effective way to monitor fertility.

  • It does not rely on different equipment such as monitors or refilling urine testing strips.

  • Does not rely on a regular schedule in which a woman is required ot check fertility signs at same every morning.

  • Not only can identify ovulation, but helps to identify when a woman is in her fertile window prior to ovulation.

  • Increases awareness of your body's natural rhythms and signs of fertility.


Best Practices for Accurate Observation

  • Check mucus every time you go to the bathroom (both before and after going).

  • Check mucus every time you go swimming, shower, or take a bath (both before and after).

  • Avoid checking during or immediately after intercourse, as semen can alter the appearance of mucus.

  • Record your observations consistently. This can be done with paper charts or on phone apps such as NFPCharting.


Factors That Can Affect Cervical Mucus

  • Medications, breastfeeding, stress, illness, and approaching menopause can alter mucus patterns.

  • Certain medications and supplements can change the quality and quantity of mucus.


Using the Cervical Mucus Method for Family Planning

  • To Conceive: Engage in intercourse during days of clear, stretchy mucus.

  • To Avoid Pregnancy: Abstain from sex during the fertile window indicated by your mucus pattern until 3 days following Peak Day.



Conclusion

The Cervical Mucus Method is a valuable tool in NFP, offering insight into your most fertile days. It requires attention and practice but can be highly effective when used correctly. If deciding to use the cervical mucus method, it is best to find an NFP instructor to teach you more detail about this method and how to make observations.
